Add a top-level changelog.md and update documentation guidance to require and describe its use. .cursor/rules/documentation-rules.mdc: expanded description and added sections for “Changelog vs Dev Log” and “Changelog Format” with Keep a Changelog guidance and an example. .cursor/rules/project-overview.mdc: reference changelog.md and clarify that docs/dev-log.md is for milestones, testing, and discoveries. changelog.md: new file with an [Unreleased] section and an initial 0.0.1 stub (notes that docs/changelog.md was moved).
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.
