mcp: validate gallery server sources and package types (#334761) * mcp: validate gallery server sources and package types Validate gallery server URLs before issuing requests and disable redirect following for server-document fetches. Reject unknown registry values before command construction while preserving usable package and remote entries across supported manifest schemas, including the Copilot NuGet mapping path. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * mcp: reuse package filtering logic Extract the repeated registry normalization and package filtering loops in the core and Copilot manifest serializers. Restore command resolution to its original construction site while retaining fail-closed handling for unsupported registry types. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * request: avoid injecting fetch implementation Keep redirect handling in the shared request implementation without extending its public function signature. Remove the dedicated fetch injection test while retaining MCP service-level redirect coverage. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * mcp: parse compatibility gallery entries independently Avoid selecting one serializer for an entire compatibility page based on a single entry. Parse each server through the shape-aware dispatcher and normalize both cursor spellings so malformed records cannot hide or truncate valid results. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * mcp: restrict gallery server fetches to HTTP Reject opaque-origin and custom-scheme server document URLs before network access. Direct gallery server fetches now require HTTP or HTTPS in addition to matching the configured gallery origin and path. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * mcp: handle optional gallery count metadata Accept compatibility gallery pages that omit optional count metadata while retaining validation for invalid supplied values. Add direct Electron request coverage proving that followRedirects zero returns an opaque redirect without requesting the target.

Show Update in Agents and protect active sessions (#332140) * chat: confirm before stopping active agent sessions Show Update in the Agents window during active sessions and guard quit, last-window close, and update restart while local Agent Host work is starting or running. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * sessions: track in-flight first requests Keep management-owned first-request state across foreground, background, headless, and quick-chat sends so shutdown protection does not depend on draft visibility or provider catalog publication. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test: make update visibility platform neutral Test the shared additional-placement context expression directly so browser suites do not instantiate the Electron-only update contribution. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * sessions: retain concurrent in-flight requests Reference-count first requests by session resource so one concurrent send cannot clear shutdown protection while another is still starting.
