[FEATURE] Update VS Code extension's session list when changes are written to the project's Claude directory (~/.claude/projects/<key>/)

Problem Statement

The VS Code extension's session list is loaded once at startup and does not refresh when new .jsonl session files are written to the project's Claude directory (~/.claude/projects/<key>/). This affects shared workflows — most notably git worktrees, where a second VS Code window shares the same Claude project directory as the primary window via symlink. Sessions created in the worktree window are written to the shared project dir but don't appear in the primary window's session list until the extension is fully restarted. There is no reload/refresh action available short of restarting VS Code.

Proposed Solution

Watch the project directory for new .jsonl files using a filesystem watcher and update the session list reactively when changes are detected.

Alternative Solutions

Expose a manual "Refresh sessions" action in the command palette as a lower-effort fix. Restarting extensions works but is cumbersome.
