Add optional movement-state fields (isMoving, isSprinting, isSneaking, isJumping, weaponDrawn, movementSpeed) to transform packets and wire them end-to-end. Plugin changes: extend F4TNetworking API and RemotePlayerState, derive movement speed/jump state on the game-thread, validate values, include fields when formatting transform JSON, and add throttled remote movement-state logging. main.cpp adds sampling, speed/vertical calculations, jump hold logic, and change-detection to avoid extra sends. Networking parsing (F4TNetworking.cpp) reads optional booleans/floats safely, preserves backwards compatibility, and clears movement-state logs on disconnect. Proxy controller includes a TODO note for future animation use. Server and docs: update protocol and packet docs, dev-log, server README, and fake_client.py to parse/display optional fields safely. Also add several .cursor rule files for coding, documentation, protocol, project overview, and testing guidance. This milestone prepares the data model for later animation/behavior work while keeping existing relay behavior unchanged.
Add a networking receive loop and in-plugin remote-player storage. Introduces F4TRemotePlayerState (header + implementation) to track assigned playerId and remote player snapshots with thread-safe access. Expands F4TNetworking to start/stop a background receive thread, parse newline-separated JSON packets (welcome, transform, disconnect), validate fields, update remote state, throttle logs, and handle socket/thread synchronization. Add nlohmann_json to xmake and plugin build. Update docs and dev log to reflect the new receive behavior and current prototype scope.
