…k cache
Persistent gRPC channel:
- Replace per-request _get_channel() context manager with lazy _channel property
- Single TLS channel reused across all mediator calls in a session
- Add close(), __enter__, __exit__, __del__ for proper lifecycle management
- Eliminates FD shutdown errors from repeated channel creation/teardown
Resumable download cache:
- New DownloadCache class saves completed chunks to hidden JSON file per serial+date
- Cache file (.{serial}-{YYYYMMDD}.download_cache.json) persists in output directory
- Each successful chunk saved immediately so progress survives crashes/timeouts
- On next run, cached chunks are loaded and skipped - only missing chunks downloaded
- Cache deleted only after full day download succeeds and CSVs are written
- CachedLog1Record/CachedLog2Record dataclasses duck-type compatible with EmopProfileLog records
- Automatic - no CLI flags or config needed
