fix(cli): filter sessions by worktree

[alex-alecu]

Why

Followup to #8971

The sessions list did not show the right sessions when someone pressed Ctrl+A. Sessions from deleted worktrees could also disappear even though they were still saved on the computer.

What changed

The sessions list now knows the exact worktree each session belongs to. Pressing Ctrl+A now filters to only the current worktree instead of guessing from path text. Sessions from deleted worktrees still show up because they are read from the local saved data. Tests cover nested worktrees and deleted worktrees so this does not break again.

How to test

Screen.Recording.2026-05-07.at.10.48.00.mov

1. Open Kilo in a repo with sessions from the root and from a worktree.
2. Run /sessions, then press Ctrl+A.
3. Check that only sessions from the current worktree are shown.
4. Delete a worktree from disk, run /sessions from the root repo, and check that its saved sessions still appear.

This logic is all changed in .33, so I'd rather wait until after that merge,b ecause we might need to implement this quite differently
