Commit Message

fix: acquire file lock before stat to prevent TOCTOU race

Move lockFile() call before f.Stat() in NewLogger so the restart
detection (size > 0 check) is protected by the exclusive lock.
Without this ordering, a concurrent process could stat size==0,
block on the lock, then incorrectly write a full header after
another process already wrote content.

Also add proper cleanup (unlock + unregister) on the stat error path.
