Teknium 3fc0cfb902 fix(gateway): make stale scoped-lock removal atomic via tombstone rename
Replace the unlink()+O_EXCL sequence in acquire_scoped_lock with an
atomic os.replace() of the stale lock to a <lock>.stale tombstone
followed by the existing O_EXCL create. With plain unlink(), two racing
starters could both judge the lock stale and the second unlink() would
silently delete the first racer's freshly-created lock — both would then
'win'. os.replace() guarantees exactly one racer claims the stale file;
the loser gets FileNotFoundError and falls through to O_EXCL, which
admits at most one winner. Tombstones are cleaned up immediately;
behavior is otherwise identical.
