This commit introduces a **control measure** within the **extension management platform** to **completely disable the loading of user-installed Copilot Chat** extensions, whether stable or prerelease. The `extensionsScannerService.ts` is updated to *skip user-installed versions* of extensions that are designated as auto-update built-ins, particularly when their auto-update mechanism is disabled. This **maintenance feature** ensures that the system strictly enforces the use of only the officially provided or controlled version of **Copilot Chat**, preventing any user-installed alternatives from being loaded. New test cases in `extensionsScannerService.test.ts` validate this exclusion logic, reinforcing the preference for system versions and the exclusion of user extensions under these conditions.

This commit **updates test stubs** for `IExtensionGalleryManifestService` and `IProductService` within the **extension gallery service tests**. Specifically, it targets `src/vs/platform/extensionManagement/test/common/extensionGalleryService.test.ts` to ensure the testing suite accurately reflects current service interfaces. This is a **test maintenance** task, improving the reliability and correctness of tests related to the **platform extension management** subsystem. The change ensures that future modifications to these services do not break existing test expectations.

This commit primarily addresses **compilation errors in tests** by updating the **extension management test suite**. Specifically, tests for `extensionsScannerService` now correctly utilize the `scanUserExtensions` method with `profileLocation`, replacing the older `scanAllUserExtensions` usage. A related **refactoring** in `src/vs/platform/extensionManagement/common/extensionsScannerService.ts` adds a non-null assertion to `productVersion.version` within a log message, enhancing code robustness. This **maintenance** work ensures the test suite remains functional and aligned with current API usage, alongside a routine update of the **Copilot submodule**.

This commit **fixes compilation errors** within the **extension gallery service tests** by refining the `createGalleryService` helper function in `extensionGalleryService.test.ts`. The update involves removing an explicit return type, adjusting the stubbing for `IRequestService` to correctly include headers, and setting the `IExtensionGalleryManifestService` status to `ExtensionGalleryManifestStatus.Available`. These **maintenance changes** ensure the **extension management platform's tests** compile and execute reliably, preventing build failures and maintaining test suite integrity.

This commit introduces the **new capability** to **auto-update built-in extensions**, allowing specific extensions shipped with the product to receive updates automatically. It enhances the **Extension Management** and **Extension Gallery Service** by adding a `autoUpdateBuiltinExtensions` product configuration, implementing version compatibility checks (major.minor), and integrating an `autoUpdate` flag into local extension data. The **Extension Scanner** is updated to handle deduplication and filtering, while the **Extension Management Service** gains logic for cleaning up stale auto-updated versions. This ensures users consistently run the latest compatible versions of critical built-in extensions, improving the overall stability and feature set of the application.

This commit introduces **Markdown support** for **session descriptions**, significantly enhancing the presentation and clarity of session information within the UI. It involves **refactoring** the `ISessionData`, `IChat`, and `ISession` interfaces to use `IMarkdownString` for their `description` fields, and updating all relevant session providers like `CopilotCLISession` and `RemoteSessionAdapter` to correctly handle and provide Markdown content. The **sessions list UI** (`sessionsList.ts`) now leverages the `markdownRendererService` to render these descriptions, with robust lifecycle management using `MutableDisposable` to prevent memory leaks when descriptions change or are cleared. This **feature enhancement** allows for richer, formatted content in session overviews, improving the user experience in **session management** and **chat interfaces**.

This commit **fixes a bug** in the **Sessions view** where the "Show All Sessions" filter's UI state would become out of sync with its persisted value after a reload. Previously, the `IsWorkspaceGroupCappedContext` context key was not properly initialized from storage, causing the menu checkmark to always appear as checked. The fix involves **binding and synchronizing** this context key with the `SessionsList` state within the `sessionsView.ts` `constructor` and `renderBody` methods. Additionally, the `Reset` action has been updated to correctly reset this context key, ensuring consistent behavior for **session management features**.

This commit **fixes several UI inconsistencies** within the **sessions management feature**, specifically addressing the **sessions title bar context menu** and **session type icons**. It ensures the `Unpin` action in the context menu accurately reflects a session's pinned state and **prevents the menu from appearing for new or unsent sessions** where actions are irrelevant. Furthermore, it **corrects the display of session icons** for `AgentSessionAdapter` by dynamically assigning specific type icons, such as `Codicon.copilot` or `Codicon.cloud`, instead of generic provider icons. This **bug fix and UI refinement** significantly improves the **user experience** by providing a more accurate and intuitive interface for interacting with various session types.

This commit delivers a **bug fix** for the **Copilot Chat Sessions** feature, specifically addressing an issue within the `CopilotPickerActionViewItemContribution`. It **corrects the method** responsible for **setting the current model**, ensuring proper initialization and selection. The change involves refining the logic around the `initModel` symbol to resolve problem #305345. This improvement enhances the reliability and correctness of model usage within Copilot chat interactions.

This commit **improves the reliability and user experience** of the **CI status widget** by gating the "Rerun Check" action. The button will now only appear if a valid GitHub Actions workflow run ID can be parsed from the check's details URL, preventing erroneous rerun attempts. This **maintenance and quality improvement** effort also exports the `parseWorkflowRunId` utility for reuse within the **GitHub Pull Request CI integration** and **expands test coverage** for both `parseWorkflowRunId` and the `rerunFailedJobs` endpoint.

This commit introduces a **new capability** to the **Sessions** extension, enabling users to **rerun individual failed CI checks** directly from the **PR checks view**. A "Rerun Check" action button is added to the `CIStatusWidget` in `ciStatusWidget.ts`, providing a convenient UI for this action. The underlying logic in `githubPullRequestCIModel.ts` extracts the workflow run ID from the check's details URL and utilizes a new `rerunFailedJobs` method in `githubPRCIFetcher.ts` to call the GitHub Actions API. This **feature enhancement** significantly improves the developer workflow by allowing quick re-execution of specific failed CI jobs without leaving the IDE.

This commit introduces a **bug fix** to the **sessions list context menu**, enabling actions to correctly operate on **all selected items** rather than just the right-clicked one. Previously, multi-selection was ignored, leading to inconsistent behavior when managing multiple sessions. The change updates `sessionsList.ts` to pass an array of selected sessions to context menu actions, and modifies seven core **session actions** in `sessionsViewActions.ts` to accept and iterate over `ISession[]`. Additionally, the `CopilotSessionContextMenuBridge` in `copilotChatSessionsActions.ts` was updated to support this multi-selection capability, significantly improving the usability of **session management** and **Copilot Chat Sessions** features.

This commit introduces a **bug fix** to the **Action Widget**'s rendering, resolving an issue where submenu group labels were incorrectly displayed as descriptions of the first action item instead of as proper section headers. It **restores correct header rendering** for `SubmenuAction` groups within `src/vs/platform/actionWidget/browser/actionList.ts` by adding a dedicated header item. Additionally, for the **sessions workspace picker**, the provider label is now specifically moved to the first child action's tooltip in `src/vs/sessions/contrib/chat/browser/sessionWorkspacePicker.ts` to ensure it renders as a description rather than an unintended header. This improves the clarity and visual hierarchy of action lists across the application, addressing a regression.

This commit delivers a **bug fix** to resolve layout inconsistencies within the **Sessions sidebar**, particularly when the **AI Customization Shortcuts Widget** toolbar undergoes dynamic changes. It introduces a new listener for `onDidChangeMenuItems` to trigger a re-layout, ensuring the sidebar correctly adjusts when toolbar items are added or removed, such as after extension activation. This work also includes minor **CSS adjustments** to reduce the sessions section's bottom margin in `sessionsViewPane.css` and a **refactoring** of the `onDidToggleCollapse` event to `onDidChangeLayout` for broader layout change handling. Ultimately, this improves the visual stability and responsiveness of the **Sessions UI**, preventing visual glitches during dynamic toolbar updates.

This commit provides a **bug fix** and **refactoring** for the **session archiving** mechanism within the `sessionsManagementService`. It specifically addresses an issue by refactoring the logic in `src/vs/sessions/contrib/sessions/browser/sessionsManagementService.ts`, removing an old conditional block that was likely causing problems. The change introduces a new disposable store and an `autorun` to properly react to and manage active session archiving, ensuring more reliable session state handling.

This commit undertakes a significant **refactoring** effort to **decouple the core sessions layer** from direct dependencies on the `AgentSessions` layer. It replaces the `AgentSessionProviders` enum with dedicated `CopilotCLISessionType` and `CopilotCloudSessionType` constants, enhancing the modularity of session type identification across various **UI components, services, and contributions**. Furthermore, the commit standardizes GitHub-related session data by introducing a generic `gitHubInfo` object, replacing direct `pullRequest` references in **session data structures and related logic** within `SessionsManagementService` and `CodeReviewService`. This **maintenance** effort simplifies internal logic, removes unused methods, and improves the overall architecture by reducing coupling within the sessions subsystem.

This commit performs significant **maintenance** and **refactoring** within the **sessions subsystem**, primarily standardizing the retrieval of session types. It introduces a `chatId` parameter to the `getSessionTypes` method across various interfaces and implementations, ensuring consistent context for session type queries. Specifically, `ISessionsProvidersService` is refactored to accept `chatId`, and the responsibility for `getSessionTypes` is largely shifted to the newly enhanced `ISessionsManagementService`. Components like `SessionTypePicker`, `copilotChatSessionsProvider`, and `remoteAgentHostSessionsProvider` are updated to align with these signature changes and service responsibilities. This **maintenance** work improves the internal architecture and consistency of session management, addressing compilation issues and making the system more robust.

This commit introduces a **new "Show Sessions Picker" command** and significantly **refactors the Sessions Title Bar Widget** to enhance session management. The title bar now leverages a dedicated sessions management service and reuses context menu definitions for improved consistency and maintainability across the **sessions UI**. Additionally, a **bug fix** ensures that the active session is always correctly included and visible within the filtered sessions list, preventing it from being inadvertently hidden. This work streamlines the **sessions feature**, offering users a more robust and intuitive way to interact with their active and available sessions.

This commit **enhances the user experience for chat sessions** by implementing the immediate display of new sessions in the UI, rather than waiting for their full commitment. It introduces a **session replacement mechanism** within the `CopilotChatSessionsProvider` and `SessionsManagementService` to seamlessly swap temporary sessions with their committed counterparts, utilizing new `setTitle` and `setStatus` methods for temporary sessions. This involved extensive **refactoring** of the **chat session lifecycle**, including the introduction of an `onDidCommitSession` event via `ChatSessionsService` and a **fix** to ensure proper disposal of temporary sessions upon commit or error, preventing resource leaks and maintaining consistent state across the `sessions` and `chat` modules.

This commit implements a **maintenance fix** to resolve a **UI layout issue** within the **sessions list**. It specifically addresses incorrect spacing by adding necessary padding to the sticky container elements in `sessionsList.css`. This ensures that sticky sections within the **sessions list** are displayed with proper visual separation, enhancing the overall readability and user experience of the **sessions management** interface.
