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.

-  BIOS loaded from system directory at CD-ROM load time via PCE_LoadCD().
+  Libretro port of Mednafen's PCE-Accurate module. BIOS loaded from system
+  directory at CD-ROM load time via PCE_LoadCD() in pce.cpp:441-460.
   Core option "pce_cdbios" selects which card image to use (default: System Card 3).
-  DetectGECD() auto-detects Games Express discs and switches to "pce.gecdbios" (gexpress.pce).
-  Arcade Card mode (pce_arcadecard option, enabled by default) extends System Card 3 with
-  extra RAM mapping via SYSCARD_ARCADE enum.
-  No hash validation on BIOS load: the core opens the file and reads it directly.
-  gexpress.pce and gecard.pce are the same ROM (Games Express CD Card); the core expects
-  gexpress.pce, libretro System.dat references gecard.pce. Both names should be provided.
-  SuperGrafx CD detection (DetectSGXCD) reads sector data to decide SGX mode but uses the
-  same BIOS files.
