Introduce default-off scaffolding for proxy visual sneak experiments: add kEnableProxyVisualSneakSync and kEnableProxyVisualSneakExperimentalGraph flags (false), include ACTOR_STANCE, and add a non-mutating ApplyProxyVisualSneakIfEnabled helper that reads proxy sneak/stance/forceSneak and emits one-time diagnostics when visual sneak is disabled. Add per-slot tracking fields (hasAppliedVisualSneakingState, hasLoggedVisualSneakDisabled, lastAppliedVisualSneakingState), ResetSlotVisualSneakTracking and calls to reset tracking when holding/reusing/disconnecting slots, and switch UpdateProxyAnimationStateDebug to accept a non-const RE::Actor&. Update docs/dev-log.md with an entry describing the change. Comments/TODOs note a future, separately approved experiment to call RE::Actor::SetSneaking(...) behind a disabled gate; current scaffolding intentionally avoids mutating actors, animation graph writes/events, or AI/package crouch logic. Build tested locally (plugin rebuild).
