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. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
