chore(test): add cross-worktree test lock and clean up dev-server test child

Browse Source 
- scripts/test-with-lock.mjs: pnpm test:locked acquires an exclusive
  ~/.fusion/test.lock (O_EXLOCK) before running pnpm test, so several
  Claude Code worktrees on the same machine serialize their vitest
  fan-out instead of saturating the box. Prints the holding PID and
  worktree path while waiting.
- dev-server-manager test children now park on stdin instead of
  setInterval so manager.shutdown() can deterministically exit them
  via stdin close, preventing orphaned node processes outliving the
  test run.
