feat: add emulator profiles and cross-reference engine (tier 2)
New two-tier architecture:
- Tier 1: Platform configs (what the UI checks) - unchanged
- Tier 2: Emulator profiles (what the code actually loads)
11 emulator profiles from source code analysis:
cemu, citra, dolphin, duckstation, flycast,
melonds, pcsx2, ppsspp, rpcs3, vita3k, xemu
Each profile documents every file the emulator loads with
source code references (file:line), hashes, and notes.
New scripts/cross_reference.py computes gaps between what
platforms declare and what emulators need.
Current gap: 200 undeclared files, 24 already in repo.
DuckStation alone recognizes 105 PS1/PS2 BIOS variants.
generate_pack.py gains --include-extras flag (future use).

feat: hle_fallback on 39 emulator profiles (266 entries)
Batch analysis of all 273 profiles to identify HLE/embedded
fallbacks. Added hle_fallback: true where the core has verified
software replacement for missing BIOS files:
- Embedded ROMs: vice (102), ep128emu (22), fuse (18), frodo (4)
- HLE BIOS: bsnes* (33 across 3 profiles), puae (9 AROS),
noods (4), melonds* (6 FreeBIOS), flycast (3 reios)
- Open-source replacements: sameboy (8), pokemini (1), gpsp (1)
- Built-in fallbacks: np2kai (7), atari800 (6 Altirra),
picodrive (3), quasi88 (4), gambatte (2)
Conservative: only added where notes or source code confirm HLE.
Skipped 50+ profiles where files are optional alternatives, not
HLE replaceable (neocd, opera, kronos, pcem, etc.)
