The z2m 2.x breaking changes required three fixes discovered during
live deployment testing on the router:
- Adapter renamed from `ezsp` to `ember` in zigbee-herdsman 4.0.0
- Config format needs `version: 4` and nested `homeassistant.enabled`
- Start script needs `ZIGBEE2MQTT_DATA` env var for correct config path
- Add `mosquitto-nossl` as package dependency (MQTT broker required)
- Direct `/dev/ttyUSB0` passthrough works; socat TCP bridge does not
Also updates project planning files (HISTORY.md, TODO.md, WIP.md,
CLAUDE.md) and rebuilds bonus feed with latest IPKs.
