c7fa1d36fb feat(movement): wire server RunRate into player MotionInterpreter
Parse ForwardSpeed from UpdateMotion (0xF74C) InterpretedMotionState.
Feed server-echoed RunRate into the player's MotionInterpreter so
get_state_velocity produces the correct speed. Previously hardcoded
at 1.0 (4.0 m/s), now matches character's Run skill.

e3f8f95dfc feat(core): port decompiled AC client MotionInterpreter — 10 methods, 45 tests
C# port of CMotionInterp from chunk_00520000.c — the AC client's
motion state machine that controls walk/run/jump/turn.

Methods ported:
- PerformMovement: top-level 5-case dispatcher
- DoMotion: process raw motion command from packet
- StopCompletely: reset to Ready (0x41000003)
- get_state_velocity: compute velocity for current interpreted state
- apply_current_movement: push velocity to PhysicsBody
- jump: initiate jump (validate + set extent + leave ground)
- get_jump_v_z: vertical jump velocity (delegates to WeenieObj)
- get_leave_ground_velocity: full 3D launch vector
- jump_is_allowed: requires Gravity + Contact + OnWalkable
- contact_allows_move: slope angle + state checks

Supporting types: MotionCommand constants, MovementType enum,
WeenieError enum, RawMotionState/InterpretedMotionState structs,
IWeenieObject interface.

412 total tests (303 core + 109 net). 45 new MotionInterpreter tests.
