horizon_mods::index (feature index): index.json's types and rules (unique
ids, https URLs, plain file names, hex SHA-256, minisign keys and
signatures, a modpack's mods present in the index), open-ended kinds
(mod, modpack, resourcepack, shader; unknown kinds kept, not offered),
revocations, and check_file: size, hash, revocation, signature and the
file's own manifest against its entry. horizon_mods::modpack reads
.hpack files: horizon-modpack.toml and an allow-list of overrides.
docs/api/mod-index.md documents both, with a sample index the tests read.
