The li3 BMS has a persistently marginal BLE link from any single fixed vantage point on this Pi (onboard adapter, a USB dongle that turned out to be BR/EDR-only, and the Athom ESPHome BT proxy even after moving it closer). Move capture into HA proper so bluetooth.async_ble_device_from_address can pick whichever known source currently has the device, instead of hardcoding one. Protocol parsing ported verbatim from li3/van-li3-battery. van-li3-battery is disabled on the Pi; its MQTT discovery entities were cleared. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
