Pull request overview

This PR updates workspace/session pickers and storage so that “recent folders” can be shared across apps (e.g. VS Code and the Agents/Sessions app) and displayed with richer metadata (grouping + secondary text).

Changes:

• Persist “recently opened” history in application-shared storage to enable cross-app sharing.
• Extend session workspace metadata (description + group) and surface VS Code recents in the sessions workspace picker.
• Update the action widget list/dropdown UI to support a dedicated detail second line, inline descriptions, and group-title display.

src/vs/sessions/contrib/chat/browser/sessionWorkspacePicker.ts:927

• URI.revive does no validation and the recent-workspace entries come from profile storage. Please use URI.from(stored.uri, true) (and handle invalid components) when building ownUris to avoid accepting malformed/untrusted URI components from storage.

		// Collect URIs already in sessions history to avoid duplicates
		const ownRecents = this._getStoredRecentWorkspaces();
		const ownUris = new Set(ownRecents.map(r => URI.revive(r.uri).toString()));

src/vs/sessions/contrib/chat/browser/sessionWorkspacePicker.ts:883

• removeRecentlyOpened returns a promise; calling it without await/void means rejections can become unhandled. Please await it or explicitly void ...catch(...) depending on whether failures should be surfaced.

	protected _removeVSCodeRecentWorkspace(selection: IWorkspaceSelection): void {
		const uri = selection.workspace.repositories[0]?.uri;
		if (!uri) {
			return;
		}
		this.workspacesService.removeRecentlyOpened([uri]);

src/vs/platform/workspaces/electron-main/workspacesHistoryMainService.ts:259

• Switching the MRU storage from StorageScope.APPLICATION to APPLICATION_SHARED will cause existing users’ recents (stored under APPLICATION) to appear empty after upgrade. Consider migrating: if shared is empty but application has data, read from the old scope once and store it into APPLICATION_SHARED (and/or fall back to the old scope for reads).

		// First try with storage service
		const storedRecentlyOpenedRaw = this.applicationStorageMainService.get(WorkspacesHistoryMainService.RECENTLY_OPENED_STORAGE_KEY, StorageScope.APPLICATION_SHARED);
		if (typeof storedRecentlyOpenedRaw === 'string') {
			try {
				storedRecentlyOpened = JSON.parse(storedRecentlyOpenedRaw);
			} catch (error) {
