yonlu 4d64b5dcfe feat(15-02): create backend/fileutil package with AtomicWrite ...

- Callback API: AtomicWrite(logger, targetPath, func(tmp *os.File) error)
- Deterministic .yj-tmp suffix for orphan cleanup
- Permission preservation (stat target, chmod temp before rename)
- Cross-device rejection via ErrCrossDevice sentinel
- Orphan cleanup on startup of each write operation
- Sync for durability before rename
