test: port 787/929 cross-module match carriers to corpus fixtures

787_xmod_variant_match.c -> r787_xmod_variant_no_default (run-exit 21),
  r787_xmod_variant_bind_default (42), r787_xmod_variant_shape_a (12)
  (pkg/errs module dirs), r787_xmod_variant_foreign_qualifier (staged
  error: w6c 'is not a variant of', w6c_ww rejects via the #95
  ambiguity guard — the carrier asserted reject polarity only)
929_match_4arm_cross_module_run.c -> r929_match_{4arm_shadowed_
  canonical,3arm_shadowed,5arm_shadowed,6arm_shadowed,4arm_mixed_kinds,
  4arm_shadowed_reverse} (run; single-file a+b packages, dropping the
  carrier's accidental doubled 'package b;' line)

929's byte-id upgrades from 994-delegated to per-fixture via
test-data-byteid; the asm-level distinct-CMPQ sentinel remains 728's
separate concern. All rows probed green on both stages.
