Phase 0: preflight green, 19/19

Baseline Torch build (USE_STANDALONE=ON, all games, Debug, PORT_VERSION_
ENDIANNESS=ON) reproduces every reference archive: 19 ROM dumps, all
0 failed / 0 not generated / 0 not in reference. Counts match the harness
README's 14-target table, and the duplicate dumps agree with each other,
which the 14-target matrix never showed.

Reference manifests also spot-checked by re-derivation from two o2r files
-- the baseline the gates measure against hasn't drifted.

+Counts match the harness README's 14-target table exactly. The **19**-dump matrix adds something
+the 14-target one never showed: the duplicate dumps agree with each other — both 1.0 dumps produce
+the same 38,390 assets against the same manifest, and all three `pal_mq_dbg` dumps produce the same

+having on record.

+Reference archives spot-checked as well — `manifest.sh` re-derivation of
+`o2r/ntsc_u_gc_b82710.o2r` (39,066 entries) and `o2r/pal_mq_dbg_079b85.o2r` (35,612) reproduces the
+committed manifests byte-for-byte. The baseline the gates measure against hasn't drifted.
