Add Atari 800 OS Rev B NTSC (CRC32 0e86d61d, canonical sysrom.c
match) and National FS-5500 disk controller ROM for openMSX.
Remove ROM_400/800_CUSTOM from retrodeck.yml (config slot key with
forward slash in name, not a real file).
Add support for Coleco Adam, Entex Adventure Vision and APF M-1000 BIOS/ROM sets in MAME and MESS metadata (multiple Adam device MCU ROMs and optional FDC/SPI variants, Advision and APF BIOS entries). Update generated metadata across the repo: README coverage numbers and per-platform coverage rows, database generated timestamp and totals (total_files 7245), and various install manifests (notably batocera.json) with new timestamps, adjusted file counts/sizes, SHA1s, repo_path fixes and an added adam_fdc_320kb.zip entry. Also update notes to reflect the new system ROM sets in the emulators entries.
RetroDECK had stale buildbot hash a17e0e01 for scummvm.zip
(from old 9.5MB build, current is 79MB) copied to cpc464.rom.
RomM had same stale hash. Updated to current verified values.
All 8 platforms now 100% OK, 0 untested.
