[Bug] Session resume picker doesn't list sessions from git worktrees

Bug Description
claude --resume picker (incl. Ctrl+A "show all") doesn't list sessions created inside git worktrees

Sessions started from inside a git worktree are stored under their own ~/.claude/projects/<encoded-worktree-path>/ bucket, separate from the main repo's bucket. The resume picker (claude -r) doesn't surface them, and Ctrl+A ("show all") also
doesn't include them.

The session files clearly exist on disk — e.g. I have buckets like -Users-roeerokah-dev-inspection-tool-fe--claude-worktrees-ticket-to-pr-5 with valid .jsonl sessions in them, but they never appear in the picker.

Workaround today: cd into the worktree path manually and run claude --resume, or pass the session id explicitly. Both require knowing where to look.

Requests:

1. Have Ctrl+A truly include every bucket under ~/.claude/projects/, or
2. Detect that the current cwd's parent repo has worktree buckets and include them in the picker, or
3. At minimum, document what Ctrl+A's scope actually is.
