Add standalone wsdebug tool for inspecting the raw Sneedchat WebSocket stream

Loads the same .env credentials as the bridge, connects to the Sneedchat
WebSocket independent of Discord, and prints every raw frame to stdout
while also appending it to a log file. Adds an OnRaw hook to sneed.Client
so the full, untruncated frame is available to callers.

+### wsdebug — standalone WebSocket inspector
+
+`wsdebug` is a separate binary that logs into Kiwi Farms using the same `.env` file as the bridge, connects directly to the Sneedchat WebSocket, and prints every raw frame it receives to stdout while also writing it to a log file. It doesn't touch Discord at all — use it to see exactly what Sneedchat is sending, independent of the bridge.
+
+Build it:
+
+```bash
+go build -o wsdebug ./cmd/wsdebug
+```
+
+Run it:
+
+```bash
+./wsdebug --env .env --log wsdebug.log --room 1
+```
+
+Flags:
+- `--env` - path to the `.env` file to load (default `.env`)
+- `--log` - path to the log file to append output to (default `wsdebug.log`)
+- `--room` - override `SNEEDCHAT_ROOM_ID` from the `.env` file (optional)
+
+Press `Ctrl+C` to stop. Every raw WebSocket frame, plus connect/disconnect/message/edit/delete events, are printed to the terminal and appended to the log file simultaneously.
