LocalBridge wraps StreamPeerTCP with 4-byte big-endian length-prefix
framing matching server/src/bridge/framing.rs. ServerProcess manages
the Rust server as a subprocess via OS.create_process(). Together
they form the D-020 IPC transport layer for ticket #79.

- decode_snapshot() reports dropped entities via push_error and returns
decode_errors count so callers can detect partial data (D-010
information boundary compliance)
- receive_bytes() warns when overwriting unconsumed snapshot, documents
latest-wins semantics
- Rename misleading test to test_encode_produces_nonempty_bytes
- Fix tick rate comment: 10 ticks/game-minute per D-031

Hoshe critical fixes:
- _action_enum_to_wire uses InputMapper.Action constants instead of
fragile integer literals; OPEN_MENU explicitly handled as client-only
- Remove int() coercion on tick/entity_id — use direct assignment since
GDScript int is signed 64-bit (safe for realistic tick values)
- Check encode result before buffering in send_input() — reject empty
bytes instead of corrupting the outbound stream
- Test snapshot now uses Protocol format {tick, entities} instead of
legacy schema; GameState updated to derive player position from
entity data; main.gd and world_renderer.gd updated accordingly
Hoshe warnings:
- 5 negative tests added (truncated bytes, wrong type, missing fields,
empty bytes, encode validation) — 20/20 tests pass
- receive_bytes signal is emitted at consume time in poll_snapshot by
design (documented in code)
Tyre suggestions:
- Remove duplicated root-level fixtures — single source of truth in
client/tests/fixtures/msgpack/
- gen_fixtures.rs writes directly to client/ directory
- Add `make fixtures` target for regeneration

Protocol.gd decodes ObserverSnapshot and PlayerInput from Rust's
rmp_serde wire format, and encodes PlayerInput for sending to server.
Handles rmp_serde enum encoding: unit variants as bare strings,
data variants as single-element maps.
8 fixture-based tests verify decode of Rust-generated fixtures,
GDScript encode/decode roundtrips, and cross-language compatibility.
All 15 tests pass (3 suites).
