Initial commit: OpenFUT Bridge

FIFA 23 reverse-engineering proxy and integration scaffold.

- Catch-all HTTP proxy that captures all incoming FIFA 23 traffic
- Known-route mapper (speculative FUT paths → Core API calls)
- Placeholder JSON responses for unmapped endpoints
- Admin endpoints: GET /_bridge/captures, GET /_bridge/unknown
- Capture persistence to captures/*.json for RE analysis
- 4 unit tests passing
