feat(phase-2): deterministic disc/.CD/PAC/LZSS extraction pipeline
- extract.py: one-command full-disc extraction (27 files: 24 Track-1 verbatim
+ 3 .DA as raw CD-DA audio from tracks 2-4) over the frozen iso9660.py
- cd_archive.py + pac.py: .CD TOC walker + PAC splitter, {index}.{type} naming
(no collisions; 447 sub-files, 1189 entries), SQV detection (98)
- lzss.py: game-semantics decoder (pos==0 terminator, -1 bias) + 5 unit tests;
138 type-4 decoded clean (0 warnings)
- manifest.py: deterministic JSON-Lines manifest (1801 artifacts) + --verify
- crosscheck.py + tools/brave-CUE/posix_shim.h: build CUE's brave from source
(GPL untouched), byte-compare; 1484 raw identical, 138/138 type-4 F6
- docs/formats.md: F5 counts (SC02=43), F2 refuted, F6 resolved, F1 type-7=139
- docs/effort-map.md + CLAUDE.md: Effort-map check rule (R7), Ultracode fix
- .gitignore: /extracted/* + !manifest/EXE exceptions; brave _build/
- install gcc 13.3.0 for the oracle
- milestone: one command extracts the full disc; MAIN.CD=49 sub-files; decoder
agrees byte-for-byte with CUE up to the game pos==0 terminator; zero ROM
staged; project version 1.1.0 -> 1.2.0
