Device info endpoint + richer node summaries (GET /api/device, MCP device_info) (#13)

README.md

@@ -28,8 +28,9 @@ All API endpoints live under the `/api` prefix:
 - `GET /api/status` — `{ connected, myNodeNum, host, port }`
 - `POST /api/send` — body `{ "text": "...", "to"?: <node number | node name | "!b" | "broadcast"> }`, returns `{ id }`. Numbers pass through as-is (integer in 1..0xffffffff); names resolve like `GET /api/nodes/:id` (exact long/short name, then unique substring) — unknown or ambiguous targets are a 400
 - `GET /api/channels` — the device's Meshtastic channels as `{ index, name, uplinkEnabled, downlinkEnabled }[]` (psk/keys are redacted; empty until the initial sync completes)
+- `GET /api/device` — device info captured during the initial sync: `{ myNodeNum, firmwareVersion?, metadata?, localConfig: {<section>: ...}, moduleConfig: {<module>: ...} }`. Key material is never exposed (security publicKey/privateKey/adminKey and network wifiPsk are replaced with `"REDACTED"`); in-memory only, reset on every bridge reconnect
 - `GET /api/messages` — message history, newest first: inbound text (`dir:'rx'`, with `from`) and our sends (`dir:'tx'`, with `to` + `status`). tx records start `pending` and move to `delivered`/`failed` (with human-readable `ackError`) when the routing ACK/NACK arrives; broadcasts stay `pending` because firmware strips want_ack before TX. In-memory only, last 100, reset on every bridge reconnect
-- `GET /api/nodes` — known mesh nodes as `{ num, longName?, shortName?, hwModel?, batteryLevel?, lastHeard: number|null, position?: { lat, lon, alt? } }[]`, sorted by node number. Collected during the initial sync plus live position updates; names/hwModel/battery appear only when reported, `lastHeard` is epoch seconds (null = never heard), and `position` only when both coordinates are known
+- `GET /api/nodes` — known mesh nodes as `{ num, longName?, shortName?, hwModel?, batteryLevel?, lastHeard: number|null, position?: { lat, lon, alt? }, snr?, hopsAway?, viaMqtt? }[]`, sorted by node number. Collected during the initial sync plus live position updates; names/hwModel/battery appear only when reported, `lastHeard` is epoch seconds (null = never heard), `position` only when both coordinates are known, and snr/hopsAway/viaMqtt only when carried by the NodeInfo
 - `GET /api/nodes/:id` — one node looked up by exact node number (numbers or numeric strings), then case-insensitive exact long/short name, else the unique case-insensitive substring match; 404 when nothing or more than one node matches
