feat: core profiles, data_dirs buildbot, cross_ref fix

profiles: amiberry (new), amiarcadia, atari800, azahar, b2, bk, blastem, bluemsx, freeintv updated with source refs, upstream field, mode field, data_directories. _data_dirs.yml: buildbot source for retroarch platforms, strip_components for nested ZIPs, freeintv-overlays fixed. cross_reference.py: data_directories-aware gap analysis, suppresses false gaps when emulator+platform share refs. refresh_data_dirs.py: ZIP strip_components support, for_platforms filter, ETag freshness for buildbot. scraper: bluemsx single ref, freeintv overlays injection. generate_pack.py: warning on missing data directory cache.

-# b2 is a standalone BBC Micro emulator by Tom Seddon. It is NOT a libretro
-# core -- there is no libretro port. The emulator uses SDL2 and Dear ImGui.
-#
-# Emulated models (src/b2/BeebConfig.cpp:211-433):
-#   - BBC Model B (with various disc interfaces: Acorn 1770, Watford, Opus)
-#   - BBC Model B+ / B+128
-#   - BBC Master 128 (MOS 3.20 and 3.50)
-#   - BBC Master Turbo (MOS 3.20 and 3.50, with 65C102 parasite)
-#   - BBC Model B + 6502 second processor
-#   - BBC Master Compact (MOS 5.00, 5.10, I5.10C)
-#   - Olivetti PC 128 S (Master Compact variant)
-#
-# ROM handling:
-#   All ROMs ship in the repo under etc/roms/. The emulator loads them via
-#   GetAssetPath("roms", path) at runtime. No external BIOS files needed.
-#   ROM paths are defined in src/b2/roms.cpp as BeebROM structs with
-#   {filename, display_name, StandardROM_enum}.
