Server sends UpdateMotion whenever an entity's motion state changes: NPCs starting a walk cycle, creatures switching to a combat stance, doors opening, a player waving, etc. Phase 6.1-6.4 already handles rendering different (stance, forward-command) pairs for the INITIAL CreateObject, but without this message NPCs freeze in whatever pose they spawned with and never transition to walking/fighting. Added UpdateMotion.TryParse with the same ServerMotionState the CreateObject path uses, reached via a slightly different outer layout (guid + instance seq + header'd MovementData; the MovementData starts with the 8-byte sequence/autonomous header this time rather than being preceded by a length field). Only the (stance, forward- command) pair is extracted — same subset CreateObject grabs. WorldSession dispatches MotionUpdated(guid, state) when a 0xF74C body parses successfully. The App-side wiring (guid→entity lookup and AnimatedEntity cycle swap) is intentionally deferred to a separate commit because it touches GameWindow which is currently being edited by the Phase 9.1 translucent-pass work. 89 Core.Net tests (was 83, +6 for UpdateMotion coverage).
