build.yml now downloads large-files release assets and copies them
to their bios/ paths (matched via .gitignore) before regenerating
the database. This fixes Batocera showing 675/680 instead of 679/680
on the remote (PS3UPDAT.PUP, dsi_nand.bin, PSVUPDAT.PUP were missing).
Local: Batocera 679/680, all others 100%.
Critical: stream large file downloads (OOM fix), fix basename match
in auto_fetch, include hashes in pack grouping fingerprint, handle
not_in_zip status in verify, fix escaped quotes in batocera parser.
Important: deduplicate shared group includes, catch coreinfo network
errors, fix NODEDUP path component match, fix CI word splitting on
spaces, replace bare except Exception in 3 files.
Minor: argparse in list_platforms, specific exceptions in download.py.
