verify_entry_existence returned no path, so RetroArch, Lakka and
RetroPie pages showed no Served by line. It now returns the resolved
path as the hash modes do. verify.py --all prints the same bytes and
its JSON is unchanged.
The install manifest marks each game data file "category": "game_data":
a platform entry only game data profile entries read, or a core file its
profile declares game data. Firmware carries no category. Every manifest
says "categorized": true so the installer can refuse an older list.
generate_pack.py --no-game-data cuts those files from the platform list
and the core profiles before the build, names each one with the cores that
read it as game data, and tags the pack _NoGameData through _narrowings.
verify.py and the pack check take the same cut, so --verify-packs and the
report describe the pack the builder wrote. Modes without a platform
(--emulator, --system alone, --from-md5) and --all-variants refuse it.
verify --platform printed N optional core files and N game data files
missing and named none, even with --verbose. --verbose now lists them as
MISSING (optional) and MISSING (game data), and without it the count line
says --verbose lists them, as the line about cores with no external file
already did.
The mode and flag matrix only tests refusals, so a flag verify
accepted and ignored, --verbose under --json, passed it. Each mode is
now checked to change its output when that flag is given.
