feat(ci): IPC serialization fixture files and cross-language tests (#271)
Five new .msgpack fixtures: snapshot_minimal, snapshot_full, player_input_move, player_input_interact, malformed. Rust generator in gen_fixtures.rs, 7 Rust validation tests in serialization.rs, GDScript cross-language test in test_ipc_fixtures.gd (22 assertions).

## D-030 Layer 1: Cross-language IPC fixture tests (#271)

## Validates that Protocol.gd decodes the #271 named fixtures identically to Rust.

## Fixtures generated by: cargo test --test gen_fixtures -- --ignored
