Add diagnostics and a log-only proxy observation for sneak state changes.
- docs/dev-log.md: Add entries documenting proxy sneak observation and local sneak detection diagnostics, scope notes, and next steps.
- plugin/src/main.cpp: Introduce SneakDetectionState, GetSneakDetectionState, and ShouldLogSneakDetection to combine API and actor-state signals; throttle diagnostic logs; use the combined finalIsSneaking in player movement state decisions; add include for ACTOR_STANCE.
- plugin/src/F4TProxyActorController.cpp: Add controller-local tracking for the represented remote player sneak state, reset helpers, and ApplyRemoteMovementStateToProxy which logs sneak transitions for the represented remote player (no visual crouch applied yet).
Notes: This change is log-only — it does not force animations or ActorState writes. Networking protocol and receive-thread behavior remain unchanged. A TODO is left to safely apply visual crouch once a supported API is confirmed.
