Subject: [PATCH] Fix: remove via_device self-reference (breaks HA 2026.9.x
 MQTT discovery)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HA 2026.9.2 added strict device registry validation rejecting discovery
messages where via_device equals identifiers[0] ('A device can not be
its own via device'). ESPSomfy sets via_device = identifiers[0], causing
all cover entities to go unavailable on every ESP32 reboot.

via_device is for proxy/gateway relationships. ESPSomfy shades ARE the
ESP32 device — there is no proxy. Removing the field is semantically
correct and has no functional impact.

Fixes #32
