- Rewrote MQTT handling with reconnect, structured logging, and Home Assistant re-discovery triggers
- Introduced modular mixins (`helpers`, `mqtt`, `amcrest_api`) for cleaner architecture
- Replaced `util.py` with internal mixin helpers and `to_gb()` conversions
- Added new `event_text` and `event_time` sensors (with `device_class: timestamp`)
- Added support for doorbell and human-detection binary sensors
- Improved reconnect logic, last-will handling, and clean shutdown on signals
- Overhauled device discovery and state publishing to use unified upsert logic
- Simplified event handling and privacy mode inference from motion/human/doorbell events
- Introduced `tools/clear_mqtt.sh` for quick topic cleanup
- Added full pyproject.toml with lint/test/dev config (Black, Ruff, Pytest)
- Embedded full metadata and image labels in Docker build
BREAKING CHANGE:
Project layout moved to `src/amcrest2mqtt/`, internal class and import paths changed.
Users must update configs and volumes to the new structure before deploying.
