Initial framework of Claude sessions in the Agents app

[TylerLeonhardt]

This is barely functional, but it is possible to chat with Claude through it.

I don't love the direction with this PR... I don't like that Claude is contributed as part of CopilotChatSessionsProvider but the problem is, CopilotChatSessionsProvider is what contributes the browseActions in order to target a local folder.

In other words, basically all session types need to go through this class. I think the API design should change to separate Claude out of Copilot CLI stuff... but in an effort to start playing with it, and pressure to get it out, this was the best option forward.

Features enabled:

• selecting the permission mode in the new chat, see bugs for what isn't working here
• sending messages to Claude in the chosen workspace
• model selection

Features not yet enabled:

• Worktree/branch pickers
• Sub-sessions or whatever they're called
• probably a lot more

Bugs:

First sent message from the welcome chat behavior is VERY strange. The chat is shown completely blank. Then I see the chat under "Unknown" section in the sessions list. I click it, it disappears after a second and reappears in the "Unknown" section. I click it again, it re-appears in the correct place... then I can start chatting with it.

Secondly, no dropdowns show in the existing chat so you can't change the permission mode once you start.

I put all of this behind a setting since it's not really ready yet.. but I wanted to get more eyes on these bugs.

Pull request overview

Introduces an initial, setting-gated integration of Claude Code sessions into the Agents app’s default sessions provider (default-copilot), including UI wiring for a Claude-specific permission-mode picker and metadata needed for correct session grouping.

Changes:

• Add a new ClaudeCodeSessionType (claude-code) and gate Claude session availability behind sessions.chatSessions.claude.enabled.
• Extend CopilotChatSessionsProvider to expose/handle Claude sessions (listing, creation, rename routing) and add a Claude permission-mode picker for the new-session controls.
• Ensure Claude extension session items provide metadata.workingDirectoryPath (when available) so sessions group under the correct workspace instead of “Unknown”; add/extend tests accordingly.
