advanced autopilot: goal mode (#320184) * advanced autopilot: goal mode * addres some comments

use risk assesment in general confirmations (#320204) * use risk assesment in general confirmations * Fix disposable leaks: check isEnabled() before resolving tool in risk badge The risk-badge factory's isEnabled() guard ran after the call sites' languageModelToolsService.getTool() lookup. With the feature disabled, getTool() was still invoked; under the shared component-fixture mock (which omits getTool), this threw inside the confirmation subpart constructor, leaving partially-constructed parts unregistered and reported as leaked disposables. Move the getTool() lookup into createToolRiskBadge() after the isEnabled() check, so it is only reached when the feature is on. The factory now takes languageModelToolsService + toolId, removing the duplicated lookup and null-check from the terminal, generic, and elicitation confirmation surfaces.

/vscode-pet (#327063) * add vscode-pet * chat: refine VS Code pet interactions - Adds product-specific, optimized chat buddies to make the pet lightweight enough to remain visible across chat surfaces. - Keeps the pet anchored to the composer so confirmations, empty states, and scroll controls remain usable without layout shifts. - Adds accessible hover and toggle interactions so the feature feels discoverable while respecting reduced motion. - Executes action-style slash commands immediately during active turns so UI commands do not become queued prompts. - Excludes GIF binaries from text hygiene checks, matching the existing treatment of other image formats.

rehaul chat input padding and spacing and icons (#323977) * rehaul chat input padding and spacing and icons * some more fixes on collapsing * address comments, fix claude * fix auto not having copilot icon * fix component fixtures * fix: implement getModelConfiguration in chat fixture model service mock Co-authored-by: justschen <54879025+justschen@users.noreply.github.com> * fix tests * Expand panel chat model picker before driving inline config in smoke test The chat model-picker rehaul added a width-driven compact layout that hides the inline model-config button (and model-name text) when the panel is narrow. The panel chat's auxiliary bar defaults below the collapse threshold, so the Chat Model Configuration smoke test could not find the config button. Widen the auxiliary bar via its leading sash until the picker leaves compact mode before interacting with the inline config UI.
