Add configurable MQTT protocol version support to allow users to choose
between MQTT v5 (default) and v3.1.1 for broker compatibility.
Changes:
- Add protocol_version option to MQTT configuration in config.yaml.sample
- Add MQTT_PROTOCOL environment variable support in helpers.py
- Update README.md with MQTT_PROTOCOL documentation
- Update mqtt-helper-graystorm package to latest version with protocol support
The protocol_version accepts "3.1.1" or "5" (default: "5") and can be
configured via config.yaml or the MQTT_PROTOCOL environment variable.

- 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)
