Apply the helper to the three other per-file FileHash constructions
(folder-walk hash, empty-archive fallback, single-file hash). The
all-empty FileHash literals are left alone since the helper would be
strictly more obscure for that case.

Add read_rar_archive_files via the existing 7zz binary (which natively
handles RAR3/RAR5 read), and collapse the per-extension reader dispatch
into an ARCHIVE_READERS dict so future formats are one entry away. Also
extract a small _make_file_hash helper to remove the repeated nested
ternaries in the inner loop.

Pull file/archive readers (zip/tar/gz/bz2/7z), CHD parsing, and the
shared libmagic MIME detector out of roms_handler.py into a new
utils/archives.py. Rename the previously underscore-prefixed
read_zip_archive_files / read_tar_archive_files to match the existing
read_7z_archive_files convention, and consolidate the duplicated
"with lock: detector.from_file()" pattern into a detect_mime_type helper.

User-configured EXCLUDED_MULTI_PARTS_EXT/FILES are intentionally not
applied to archive internal files. Archives are curated ROM sets where
every file is relevant — user custom exclusions (e.g. "bin") could
silently produce incorrect composite hashes. Only the hardcoded
DEFAULT_EXCLUDED_FILES/EXTENSIONS (junk like .DS_Store, gamelist.xml)
are applied.

- Use AnyioPath.stat() instead of os.path.getmtime in async context (ASYNC240)
- Add assert to narrow rom_md5_h/rom_sha1_h from HASH|None to HASH (mypy/union-attr)
- Auto-formatted long log.error calls in archive_7zip.py (ruff)

CHD files now follow the same hash logic as all other file types — CRC32,
MD5, and SHA1 are computed from raw container bytes. This allows
ScreenScraper to log KO entries for unrecognised CHD files, which it
could not do when only the disc-data SHA1 was being computed.
The CHD header SHA1 (disc-data SHA1) is separately extracted and stored
in a new chd_sha1_hash field on RomFile, with a migration adding the
column to rom_files. Hasheous receives only this disc-data SHA1 (no
CRC/MD5) since it indexes disc-based games by disc-data SHA1, not raw
file hashes.
The RAHasher multi-file path now passes the largest CHD directly instead
of a /* wildcard, which RAHasher cannot expand. Hash computations are
wrapped in asyncio.to_thread to avoid blocking the event loop during
large reads.
Hash-lookup metadata handlers (ScreenScraper, Hasheous, Playmatch) now
fall back to rom.files (stored DB hashes) when fs_rom files are not
rehashed, fixing hash-based matching for UNMATCHED and UPDATE scan types.
The Disc SHA-1 is displayed in the ROM detail view for both single-file
(FileInfo.vue) and multi-file (FileSelectItem.vue) CHD games.
Replace the single HIGH_PRIO_STRUCTURE_PATH config attribute with two
glob patterns (STRUCTURE_PATH_A = roms/*, STRUCTURE_PATH_B = */roms) and
update all call sites to detect Structure B via glob.glob, defaulting to
Structure A when no match is found.

Callers now pass the full platform dict and rom.fs_extension; the service
normalizes the extension (optional leading dot, case-insensitive) before
checking the compressed-archive skip set, so ROMs stored with bare
extensions like "zip" correctly hit the skip path.

RAHasher was being spawned for every hashable ROM regardless of file
type. When the source file is a zip/7z/tar and the RA platform needs
an on-disk disc image (PSX, PS2, PSP, Saturn, Dreamcast, Sega CD,
3DO, PC-FX, Neo Geo CD, TurboGrafx CD, Atari Jaguar CD, Wii), the
subprocess fails with "Unsupported console for buffer hash: {id}"
after paying full process-spawn overhead per ROM — a serious slowdown
when indexing large zipped collections (e.g. myrient PS2/PSP sets).
calculate_hash now short-circuits those combinations with a debug log
and no subprocess. Raw disc images (.iso, .chd, .cue/.bin) and
archives on cartridge platforms still go through RAHasher as before.
Also centralize COMPRESSED_FILE_EXTENSIONS in utils/filesystem.py so
roms_handler (is_compressed_file / hashing), rahasher (skip logic),
and feeds (PKGi passthrough) share one source of truth. The shared
set adds .rar, which is_compressed_file now recognizes too.
