vgsp: m178 GR launch reliability + diagnostics; tools: pin latching robustness

Kernel: authorship instrumentation + swrel gate for in-flight GR release VAs;
first-poll shortening + fast extended re-arm (params gr_retry_fast=1,
gr_first_poll_ms=2500); per-attempt win0 bank recompute + shadow recopy in the
outcome-retry loop; poll-break/deposit-readback diagnostics; C1-C10 sema
diagnostics (crel-entry, relx, opdef-clear, walk, pub-adv, hold-fallback,
busy-defer, CAND-OVERWRITE, inline recs); busy-defer hold instead of
software-release consume; counter fast path; QMD word 48/49 skip.
Tools: heartbeat thread, scanner-alive probe on reinstall, full periodic
re-assert, #nopid handling, per-client reset fix (debounce), dead-pid drop,
supervisor grace+threshold.
