feat(firmware): ESP32-S3 firmware skeleton with CSI/BLE/WebSocket
- State machine: 7-state lifecycle (BOOT→WIFI→DISCOVERY→CONNECTED,
degraded modes WIFI_LOST/MOTHERSHIP_UNAVAILABLE/CAPTIVE_PORTAL)
- WiFi: STA connection with exponential backoff, mDNS discovery with
cached IP fallback, captive portal AP for provisioning
- WebSocket: bidirectional comms, binary CSI frames (24B header + I/Q),
JSON hello/health/ble/ota_status upstream, role/config/ota/reboot
downstream, OTA task with progress reporting
- CSI: promiscuous mode capture, queue-based processing, passive BSSID
filter, on-device variance tracking (Welford's) for motion hints
- BLE: passive scanning on Core 0, 60-device cache, 5s reporting
- NVS: 15-key schema with versioning, role/rate persistence
Complete: ESP32 firmware skeleton, passive radar, BLE scanning
Remaining: Dashboard skeleton, Docker packaging (Phase 1 items 5-6)
