* sfu/buffer: parse the dependency descriptor without allocating Every VP9 and AV1 SVC packet allocated six objects in the dependency descriptor parse: the descriptor, a clone of the frame template with its three slices, a resolution copy, and a frame entity that took the address of a parameter. The pooled ExtDependencyDescriptor now owns the storage for the descriptor, the template and the resolution, with fixed arrays for the template's slices. The reader copies the matching template into that storage. Delta frame parse: 6 allocs, 176 B, 174 ns -> 0 allocs, 0 B, 122 ns. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * sfu/dd: never copy a parsed frame into a structure template A caller can hand Unmarshal a descriptor whose FrameDependencies points at one of the structure's templates. Copying the packet's custom fields into it would change the template for every later packet, so the reader allocates a fresh template in that case.
