Pull request overview

Updates the extension’s chat context integration to match the newer VS Code proposed “chat context provider” API split (workspace vs explicit vs resource), and adjusts provider registrations/types accordingly.

Changes:

• Split PR chat context into a new WorkspaceContextProvider (workspace context) plus an updated PullRequestContextProvider (explicit + resource context).
• Update IssueContextProvider to implement the new explicit/resource provider interfaces and method names.
• Update chat context provider proposed typings and switch registrations in extension.ts to the new registerChat*ContextProvider APIs.

src/lm/pullRequestContextProvider.ts:106

• provideExplicitChatContext unconditionally uses this._reposManager.folderManagers[0]. If there are no folder managers this will throw, and in multi-root workspaces it ignores other repositories. Consider returning an empty list when there are no repos and aggregating PRs across all folderManagers.

	async provideExplicitChatContext(_token: vscode.CancellationToken): Promise<PRChatContextItem[]> {
		const prs = await this._prsTreeModel.getAllPullRequests(this._reposManager.folderManagers[0], false);
		return prs.items.map(pr => {
			return this._prToUnresolvedContext(pr);
		});

src/extension.ts:280

• The chat context provider registrations for githubissue also aren’t being disposed (the returned Disposables are ignored). Add these registration disposables (and any disposable providers, if needed) to context.subscriptions.

	const issueContextProvider = new IssueContextProvider(issueStateManager, reposManager, context);
	vscode.chat.registerChatExplicitContextProvider('githubissue', issueContextProvider);
	vscode.chat.registerChatResourceContextProvider({ scheme: 'webview-panel', pattern: '**/webview-IssueOverview**' }, 'githubissue', issueContextProvider);
