fix: improve worktree/session handling in cmd_start, cmd_continue, and cmd_init

cmd_continue:
- If worktree is missing but session exists, remove stale session and call cmd_start automatically
- This allows automatic recovery without user intervention

cmd_start:
- Check BOTH worktree AND session existence
- If only worktree exists (not session): remove worktree, recreate both
- If only session exists (not worktree): remove session, recreate both
- If both exist: tell user to use continue

cmd_init --force:
- Now actually destroys existing base and pm-agent sessions before reinitializing

Daemon:
- Fixed wrong path in check_task_completion ($HOME/.kugetsu-worktrees -> $WORKTREES_DIR)
