Shokunin eb301961f6 Render thread core: SPSC command ring, frame bound, sync-point hand-off

Backend-neutral core for the opt-in [video] render_thread: the emulation
thread appends records to a single-producer/single-consumer ring and the
render thread replays them in order with the graphics context current.
rt_frame_end bounds closed frames in flight (backpressure), the render
thread can tell a frame is stale, and rt_acquire is the sync point:
drain, then move the context to the emulation thread until rt_release.
No lock is held while a record executes.

render_thread_test drives it with a fake executor and context token:
ordering and payload integrity across ring wraps, oversize refusal, the
in-flight bound under a slow consumer, stale detection, randomized
acquire/release interleaving and stop while held (TSan clean).
