* Filament Error Handling Remediation and noexcept Cleanup
- Replaced assert_invariant with FILAMENT_CHECK_PRECONDITION in
Renderer::beginFrame for caller bugs.
- Removed noexcept from Camera::setCustomProjection to allow precondition
checks to throw.
- Removed noexcept from Texture and InstanceBuffer methods using precondition
checks.
- Documented silent clamping in View::setBloomOptions.
- Clarified comment in FrameGraphResources regarding preconditions.
- Refined MaterialInstance::commit to split texture loop into check and update
passes, preventing partial state changes on precondition failure.
* backend: Propagate backend thread exceptions to the main thread.
Introduce a mechanism to catch exceptions thrown on the backend thread and
rethrow them on the main thread. This prevents deadlocks and allows the
application to handle fatal backend failures gracefully.
- Consolidate synchronization primitives in DriverBase.
- Add mHasUnrecoverableError flag to interrupt blocked fence waits.
- Optimize waitForFence to avoid extra atomic reads in common paths.
- Propagate FenceStatus::ERROR across all backends.
- CommandBufferQueue now stores a std::exception_ptr when the backend fails.
- The backend enters a "zombie" state on failure, skipping further command
execution but allowing clean shutdown.
- Public APIs in Renderer and Engine now check for stored exceptions and
rethrow them, documented with @throws.
- Guarded by __EXCEPTIONS to ensure no overhead when exceptions are disabled.
- Add unit test for fence interruption and document new APIs.
BUGS=[407545700]
* feat: harden backend exceptions and add hasUnrecoverableFailure API
- Update Renderer::beginFrame() and Renderer::shouldRenderFrame() to
return false early if an unrecoverable backend exception has been
delivered to the main thread.
- Document the new return behavior for beginFrame() and
shouldRenderFrame() in Renderer.h.
- Add Engine::hasUnrecoverableFailure() to the public API to allow
apps to check for fatal errors without relying on exceptions.
- Implement hasUnrecoverableFailure() in FEngine by delegating to
CommandBufferQueue.
- Expose Engine::hasUnrecoverableFailure() to Java bindings
(Engine.java and JNI).
- Expose Engine::hasUnrecoverableFailure() to JavaScript bindings
(jsbindings.cpp).
* java: propagate C++ Panics & exceptions to JAVA
* Add JNI for TransformManager.getChildCount(), TransformManager.getChildren() and scene.hasEntity()
* Update RELEASE_NOTES.md
* Fixes
* Change getChildren to take a nullable array
* Remove no params TransformManager.getChildren()
* Update RELEASE_NOTES.md

Augment the TransformManager so it can maintain the 4th column as
double precision; we accomplish this by storing an extra float3 per matrix.
It's calculated as `doubleTranslation - float3{doubleTranslation}`.
We also add methods to set and get a transform as mat4, internally only
the 4th column is kept as double precision.
Finally when we calculate the worldTransform, we take this extra data into
account, but only for calculating the new 4th column, so the extra work
is small.
math/mathwfd.h forward declares all {mat|vec}{2|3|4}<> classes,
which allows us to remove their respective #include in a lot of
our public headers.
Our math headers are full of templates, so this should help build times
a bit.
Also we want to keep the public headers as minimalist as possible.
