- job_worker.rs: add upsert_processor_result when output file exists
- job_worker.rs: add load JSON and store to pre_chunks when output exists
- rule3_ingest.rs: fix SQL bind order (scene_number was occupying chunk_type slot)
- files.rs: fix unregister WHERE clause (uuid -> file_uuid) + add pre_chunks delete
- asrx_self/main_fixed.py: fix KeyError (s['start'] -> s['start_time'])
- wrapper_worker_playground.sh: add Worker launchd script
- com.momentry.playground.plist: add Playground launchd config
