gr: r410 wedge quiet window - bounded idle hold before retrying a lane whose previous launch also no-wrote (r416: 58-launch sticky wedge clears after ~50 s quiet); wedge counters in state; wedge_recover v2 unmask

The r416 boot reproduced the sticky no-execute wedge inside 60 s: 58
consecutive launches accepted zero writes while the lane stayed busy
(wedge_recover v1's deterministic verify masked every one of them), and
the first launches were green again only after the lane sat idle ~52 s.
Both r409 (~37 s idle heal) and r416 therefore show the wedge clears on
idleness and persists under back-to-back retries (r154/r409), so the
retry loop now holds a quiet window (gsp_phys_gr_wedge_quiet_ms, default
20000, doubling on the second quiet retry, 0 disables) before the normal
fresh-bank + resched retry when the previous launch also no-wrote. The
whole-launch stall budget is relaxed only on this bounded recovery path.
NOWRITE lines now carry the consecutive streak and quiet/heal counters,
and the state file shows nw_streak/wedge_quiet/wedge_heals.

wedge_recover v2 mutates the inputs every iteration so a stale (never
executed) launch can no longer match the expected values, and classifies
the readback STALE-PREV(NOWRITE) vs OTHER/PARTIAL.
