VOID Engine 2.1.0

   Camera
   - Cameras attached to a batcher now update automatically during rendering.
   - Added protected BaseCamera.OnUpdate(FrameTime) for custom camera behavior.
   - Cameras update at most once per rendered frame even when shared by multiple batchers.
   - Removed the need for game code to manually update attached cameras.
   - Camera timing now uses the rendered-frame timing context.

   Frame Timing
   - Reworked FrameTime to own and manage VOID's game-loop timing state.
   - Fixed timestep updates now receive the configured fixed update interval.
   - Rendering receives the actual elapsed frame time even when fixed timestep mode is enabled.
   - Variable timestep mode continues to use actual elapsed frame time for both update and rendering.
   - DeltaTime remains time-scale aware.
   - ElapsedTime and UnscaledDeltaTime expose the current unscaled timing phase.
   - TotalTime, accumulator, interpolation alpha, FPS, and slow-frame tracking remain available through FrameTime.
   - Engine update systems continue to receive FrameTime rather than standalone delta values.

   Coroutines
   - Replaced the previous coroutine implementation with a VOID-native IEnumerator coroutine runner.
   - Added nested coroutine chaining through yield return IEnumerator.
   - Nested child routines can chain to arbitrary practical depth.
   - Parent routines resume after their child routine completes.
   - Root coroutine handles remain valid while nested children are executing.
   - Stopping a root coroutine now stops and cleans up its entire active child chain.
   - Coroutine cleanup disposes nested routines from the deepest child back to the root.
   - Starting and stopping coroutines during a coroutine update is supported safely.
   - CoroutineManager now uses FrameTime for timing.
   - Numeric float, double, and int yields continue to represent scaled-time delays.
   - CoroutineHandle remains an immutable readonly struct.
   - Coroutine Count reports active root coroutines only.

   Beacons
   - BeaconHandle payload data is now exposed as a read-only view.
   - BeaconHandle is safe when default initialized.
   - Added Count for payload item count.
   - Improved Get and TryGet payload handling.
   - Beacon subscription mutation is now synchronized while keeping publishing on the existing fast multicast Action<BeaconHandle> path.
   - Publishing remains synchronous and does not manually iterate subscribers.

   Beacon Extensions
   - Added BeaconManager.PublishDelay for delayed string and enum topic publishing.
   - Delayed publishing uses the normal VOID coroutine system and scaled game time.
   - PublishDelay returns a CoroutineHandle so a pending publish can be stopped.
   - Added BeaconHandle typed payload extensions for one through five payload values.
   - Added Get, GetOr, TryGet, Has, IsTopic, HasData, and IsEmpty convenience helpers.
   - Multi-value payload helpers use direct positional access without payload scanning or enumeration.

   Game Loop
   - Updated the game loop to distinguish fixed-update timing from rendered-frame timing.
   - Added render-frame tracking used by automatic camera updates.
   - Preserved graceful shutdown checks so updates and rendering do not continue after the window closes.
