* Address review: clear wakeupPending at tick start, guard CarbonEmissionsHack subscriptions
- Clear _wakeupPending at start of TimerTick so wakeups already processed
by the current tick don't force an unnecessary extra tick
- Guard CarbonEmissionsHack against duplicate subscriptions using a private
attached property

* Fix lock-order inversion in Add/Remove vs TimerTick
Move Wakeup() and Stop() calls outside the _items lock in Add/Remove
to prevent deadlock with TimerTick which acquires _timerLock then _items.
Add/Remove are UI-thread-only so the extracted logic remains safe.

* Address review: remove unused usings, guard double Stop(), fix SleepLoop extra frame
- Remove unused using directives from IRenderLoopTask.cs
- Guard TimerTick Stop() with _running check to prevent double Stop()
when Remove() already stopped the timer
- SleepLoopRenderTimer: use WaitOne(timeout) instead of Thread.Sleep
so Stop() can interrupt the sleep, and recheck _stopped before Tick

* Fix DisplayLinkTimer foreground handler bypassing render loop state
Only resume the display link on WillEnterForeground if the timer was
calling Start() to avoid setting _stopped=false when the render loop
had the timer stopped.

* Fix DisplayLinkTimer thread safety, revert global NU5104 suppression
- Stop() now only sets _stopped flag; OnLinkTick() self-pauses the
CADisplayLink from the timer thread to avoid thread-affinity issues
- Revert NU5104 global suppression in SharedVersion.props

* Cap _ticksSinceLastCommit to prevent int overflow
Stop incrementing once it reaches CommitGraceTicks to prevent
wrapping negative and keeping the render loop awake indefinitely.

* refactor: remove Start/Stop from IRenderTimer, merge into Tick setter
Timer start/stop is now controlled entirely by setting the Tick
property: non-null starts, null stops. This eliminates the explicit
Start()/Stop() methods from IRenderTimer, making the API simpler.
DefaultRenderLoop controls the timer purely through Tick assignment
under its _timerLock. A new _hasItems flag tracks subscriber presence
since Tick is now transient (null when idle).

* fix: address review comments on timer thread safety and guards
- ChoreographerTimer: add _frameCallbackActive guard to prevent double
PostFrameCallback from both Tick setter and SubscribeView
- ServerCompositor: cap _ticksSinceLastCommit at int.MaxValue
- SleepLoopRenderTimer: make _tick volatile, remove _stopped recheck
(guard moved to DefaultRenderLoop)
- DefaultRenderLoop: add _running check at tick start to drop late ticks
- ThreadProxyRenderTimer: add lock for internal state manipulation
- DisplayLinkTimer: add lock for all internal state manipulation
- Re-add NU5104 suppression to SharedVersion.props

* Remove CarbonEmissionsHack, revert iOS/Android timers to always-ticking
- Delete CarbonEmissionsHack class and its XAML reference
- Revert DisplayLinkTimer (iOS) to original always-ticking implementation
- Revert ChoreographerTimer (Android) to original always-ticking implementation
- Add TODO comments for future start/stop on RenderLoop request

* Fix DirectCompositionConnection WaitOne not respecting process exit cancellation
Use WaitHandle.WaitAny with both _wakeEvent and cts.Token.WaitHandle so
the loop can exit when ProcessExit fires while the timer is stopped.

- animation/layout/render cycle is now managed from a central location
- animations are now throttled if animation/layout/render pass takes longer than a frame which previously caused a soft-freeze with input not being processed
- the public API is trimmed to make sure that we can make other planned changes during the 11.x support cycle
"Changelog":
- IClock is hidden and is planned to be replaced later
- Animator classes are hidden and are planned to be refactored later
- IAnimation members are hidden, it's supposed to be a marker interface for Style.Animations collection now, to start animations manually use Animation.RunAsync
- Sealed several classes in Avalonia.Animation namespace
- Spring class is removed from the public API (it wasn't possible to use it directly in a meaningful way anyway)
- Sealed brushes, transforms, effects and drawings
- Removed separate dispatcher priorities for Layout and Composition, everything now happens from a central place with Render priority (same as WPF)
- - some private "hook" priorities are added for now, those will be removed later
- IRenderLoop is hidden and removed from locator
- IRenderer is hidden (the plan is to remove that concept later)
- - Renderer.Start/Stop exposed as StartRendering/StopRendering on the toplevel (will be on a CompositionTarget/PresentationSource-like type later)
- - Renderer.Diagnistics exposed as RendererDiagnostics (same)
- - Renderer is no longer created by the platform code and is created by TopLevel itself
- - From the user-code hit-testing should be done by VisualExtensions.GetVisual(s)At, which has the same features
- - For unit tests a separate IHitTester interface is added which can be changed for a particular toplevel
- ILayoutManager is hidden
- - LayoutManager.ExecuteLayoutPass() exposed as TopLevel.UpdateLayout()
- Custom animators now have a separate base class that only deals with interpolation
Minor improvements:
- Compositor has a mode that doesn't use DispatcherTimers, useful for unit tests
- Introduced ScopedTestBase that auto-resets the locator when test is finished
