ik 4ac50db1db A02: Atomic check-and-reserve with lockfile for cross-process coordination
- Single exclusive lock covers read-check-write in one critical section
- Lockfile pattern ensures cross-process mutual exclusion
- Atomic write via temp file + rename after unlock
- Flush + fsync before unlock to prevent data loss
- Real multi-process test: 3 concurrent processes get exactly 1 reservation
- 111 Python tests pass (+2 new tests)
