fix: improve worktree/session handling in cmd_start and cmd_continue

cmd_continue:
- Check if worktree exists before continuing
- If worktree is missing, remove stale session and exit with error
- Tell user to use cmd_start instead

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

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