fix: make delete CLI path a --path option, clarify FTS guard comment

Reviewer feedback:
- path as a second positional arg was unreachable (Click assigns
  left-to-right, so a path string would land in repo_id). Now --path/-p.
- Added comment explaining fts is always initialized in lifespan, so
  the None guard is purely defensive.
