Replace string-matching disconnect detection with explicit
BridgeError::Disconnected variant. Add TcpBridge::accept_on(listener)
that takes a pre-bound TcpListener, eliminating the 100ms sleep hack
in TCP tests. Send errors now also trigger ServerRunning=false.
Add trace logging to generate_snapshot for entity count visibility.

Client-side Protocol.gd expects rmp_serde::to_vec_named() (maps with
string keys), but LocalBridge was using to_vec() (compact positional
arrays). Fix send_snapshot and update all test serialization calls to
match actual wire format. Also change EOF from Ok(vec![]) to
BridgeError::Transport so bridge systems can detect disconnects.

Replace .lock().unwrap() with .expect("mutex poisoned") in LocalBridge
for clearer panic messages. Document 16MB MAX_MESSAGE_SIZE rationale
in framing.rs with entity count sizing analysis.
Addresses Hoshe PR review suggestions.

Length-prefixed MessagePack framing (4-byte BE length + payload),
LocalBridge struct implementing SimBridge trait over Unix domain
sockets, BridgeResource wrapper for ECS integration. Adds Io
error variant to BridgeError. Two integration tests verify
snapshot and input round-trips over real sockets.
