feat(espnow): Pi bridge client, binary wire, and espnow-sender firmware

Browse Source 
Replace serial/Wi-Fi driver transport paths with WebSocket bridge client,
binary espnow_wire delivery, device announce registry, and restructured
espnow-sender (AP + broadcast passthrough). Includes docs and tests.
