Read the English 1.0 and Australian cartridges besides 1.1 (#84)

PRET's crystal and crystal_au builds reproduce both retail cartridges,
and every label the profile pins keeps its address in all three;
check:reference now verifies that when the rebuilds are present. The
revision comes from the header. Revision 1.0's Battle Tower draws only
the first 21 trainers and picks its texts' gender from the name's sixth
character, checked against each cartridge. A native backup imports
across the three, which share every map, event and object.

+Local-ROM tests use `Pokemon - Crystal Version (UE) (V1.1) [C][!].gbc` at the root, or `CRYSTAL_ROM_PATH`, which may also point to PRET's 1.0 or Australian rebuild (`make -C .reference/pokecrystal crystal crystal_au`); `tests/revisions.test.ts` and `tests/reference-revisions.spec.ts` use those rebuilds when they are present.

 [CI checks](https://git.azuze.fr/kawa/Crystal/actions?workflow=checks.yml) run on pushes and pull requests, or manually from Actions. The [workflow](.gitea/workflows/checks.yml) uses the shared `docker-build` runner with Node 22 in a Debian container. It installs from the lockfile, runs synthetic unit and Chromium/WebKit browser tests, builds both applications, and checks vendor integrity and native release isolation. `CRYSTAL_ROM_PATH` points to a verified absent file, so ROM-dependent tests skip; `check:reference` runs separately with the private ROM and reference build.
