Complete remaining cubic-dev-ai fixes

Addresses the last three cubic-dev-ai suggestions that weren't auto-fixed:

1. Fix peername guard in websocket_server.py:
   - Check if peername exists and has length before indexing
   - Prevents crash when transport lacks peer data

2. Fix CLAUDE.md test paths:
   - Update from non-existent tests/client paths
   - Point to actual plugin test directories

3. Fix JSON-RPC example in README.md:
   - Update example to show actual output (stringified params)
   - Add note explaining the behavior

All WebSocket tests passing (9/9).
Ready for PR merge.
