flutter_scene 0.22.0

• Node.position, Node.rotation, and Node.scale read and write the local transform one component at a time, and editing a returned copy in place throws in debug builds rather than silently doing nothing.
• Node.mutateLocalTransform edits the local matrix in place through a callback and marks the node dirty, the correct way to reach for the raw matrix.
• A frame that draws nothing now prints once in debug builds naming the likely cause (not ready, empty region, no views composite to screen, no visible meshes, or a layer mask matching nothing).
• Degenerate cameras now assert in debug builds, catching a view direction of zero length, an up parallel to it, and a field of view passed in degrees.
• The web backend now throws on a bind to a shader uniform or texture name that does not exist, matching native, instead of silently sampling whatever was bound last.
• SkinnedGeometry.uploadVertexData and setCustomAttribute now throw on a buffer whose length does not match the vertex count, instead of rendering garbage.
• A Mesh whose primitive geometry is replaced now recomputes its bounds on its own, rather than over-culling until markLocalBoundsDirty is called.
• An AnimationClip that binds zero of its channels now asserts in debug builds, naming the wanted nodes, since it otherwise plays while nothing moves.
• Fixed the second and every later flutter run rendering nothing, from two hook invocations writing the same shader bundle filenames with different backend trims.
• Fixed Scene.initializeStaticResources() reporting ready when the shader bundle loaded but held nothing this engine can read.
• Fixed dart run flutter_scene:init then flutter run failing on a new app with "Flutter failed to list directory".
• Fixed Node.clone() sharing the original's transform matrix.
• Fixed the skinning joints texture being too narrow for small joint counts, which duplicated matrix columns.
• Fixed ParticleSystem.reset() not restarting its random stream.
• Mutating Node.localTransform in place without markTransformDirty() now throws in debug builds instead of silently doing nothing.
• SceneViewsBuilder is now exported.
• Documentation fixes for names that no longer exist (Environment, loadModel, the master channel requirement), plus a readme scene that needs no asset files and a list of the built-in geometry.
