Adds user-facing worktree management commands:
- bd worktree create <name> - creates worktree with beads redirect
- bd worktree list - shows all worktrees and their beads state
- bd worktree remove <name> - removes worktree with safety checks
- bd worktree info - shows current worktree info
The create command automatically sets up .beads/redirect to point to
the main repos .beads directory, ensuring all worktrees share
the same issue database. This enables parallel development with
multiple agents or features.
