feat(phase-31): wave I — 44/44 banked (perfect sweep), R22 213/213

- 44 atlas mass cards on ov_SC07_007 -> 44/44 standalone MATCH (independently re-verified),
  symfix clean on all 44, and the binary builds BYTE-IDENTICAL with every draft substituted.
- includes a fleet-shared engine_core.h arity fix (func_8017FD2C(u8*) -> ()), so this batch
  needed the full-fleet proof: make clean && extract-all && check-all -> 213/213.
- stubs 11,751 -> 11,706.
- TOOLING NOTE for next session: gate_lane SWALLOWS gate_stage's stderr. Two gate attempts
  reported 'banked 0, near 0, failed 0' -- an unreported crash that reads exactly like a
  legitimate 'nothing banked'. Running gate_stage directly surfaced the real cause at once
  (corpus.CorpusError naming 16 missing .s files, fallout from my own make clean). gate_lane
  should surface stderr / distinguish CRASH from NOTHING-BANKED.
