vgsp-gr: m156 integrate bigpath+dual; qmdwin double-buffer (E3); warm sem push on zero-write retry (E5)
- Merge bigpath (B-2 64 MiB grown data-bounce region for large operands)
and dual (per-mdev separation G1-G8a) into master.
- E3: the inline-QMD destination is now double-buffered (0x107000/0x108000,
same proven PTE fetch line); launches alternate banks by submission epoch
so a QMD-unit look-ahead read of the previous launch's page can never race
this launch's rewrite.
- E5: on the first zero-write outcome retry the module pushes the proven
stage-4 GR semaphore block; OK = engine alive (retry can recover), timeout
= engine wedged for the boot and further retries are skipped (saves ~20 s),
counted in work_gr sem_wedged.
