Initial commit: OpenFUT Core + Bridge scaffold

Two-repo monorepo for an offline FUT backend inspired by SPT.

openfut-core: game-independent REST API backend (Axum, SQLite, SQLx)
- 19 API endpoints: auth, profiles, clubs, cards, packs, squads,
  objectives, SBCs, match rewards, NPC market, statistics
- JSON-driven card/pack/objective/SBC data (fully moddable)
- SQLx migrations, weighted pack generator, SBC validation engine
- 5 integration tests passing

openfut-bridge: FIFA 23 traffic proxy + reverse-engineering scaffold
- Catch-all HTTP proxy with request capture to captures/
- Known-route mapper (FUT paths → Core API calls)
- Placeholder responses for unknown endpoints
- Admin endpoints: captures, unknown endpoint list
- 4 unit tests passing

cargo fmt ✓  cargo clippy -D warnings ✓  cargo test ✓
