fix: source-verified corrections on 7 profiles

beetle_pce: +core_classification, +upstream, cores=[mednafen_pce],
alt_names→aliases. 6 files confirmed loaded by code.
mame: removed 19 phantom XaviX entries (MACHINE_IS_BIOS_ROOT commented
out in source). 80 real BIOS sets verified.
mame2010: fixed galgbios.zip source_ref, documented cheat.zip as
non-functional in libretro port (cheatpath never initialized).
ishiiruka: trimmed verbose advisory notes to factual descriptions.
mamearcade: added system: field to 29 bios_zip entries, 24 new systems.
mednafen_ngp: removed redundant cores: on alias, added note:.
mednafen_gba: normalized validation format to flow sequence.
