Move shared-memory ownership, LGMP session handling, queue access, and DMA setup behind a transport interface. The LGMP backend preserves the existing zero-copy frame and DMA paths while owning its lgmp:* options. Expose the initialized EGL context through a versioned renderer interop record for future accelerated decode backends. Add an LGMP-independent, deterministic test transport for graphics-pipeline validation.
