The backends deliberately turn a wedged GPU into a bounded error so the
caller can reset in place, but only the native plane ever did: on the
GameStream path every submit/poll error propagated straight out of the
video loop, costing Moonlight clients a full disconnect/reconnect. Port
the native ladder (bounded resets + backoff + silent-wedge watchdog,
same field-lesson backoff curve).
Also keep the drop-recovery keyframe armed until it actually EMITS: it
was consumed on read, so the coalesce gate could swallow it for good —
leaving duplicate wire indices in the encoder's reference table for a
later RFI to anchor on, exactly the stale-anchor case rfi.rs exists to
prevent, and it opened only under congestion + loss, which is when RFI
fires.
