Abdessamad Derraz d5daf98e5e feat: hle_fallback field + launcher filtering in verify
Added hle_fallback: true/false per file in emulator profiles.
When a core has HLE and the file is missing, severity downgrades
to INFO instead of CRITICAL — core works without it.

verify.py builds an HLE index from emulator profiles and applies
it during severity computation. Cross-reference now skips launcher
profiles (type: launcher) and includes hle_fallback in undeclared
file reports.

33 E2E tests (4 new: HLE severity, HLE index, launcher skip,
cross-ref HLE). 0 regressions.

Based on source code analysis:
- RetroArch core_info.c:2233 — existence check only, no blocking
- PCSX ReARMed psxbios.c:28 — full HLE BIOS replacement
- Dolphin CommonPaths.h — all files optional with HLE
- snes9x — DSP HLE built-in, coprocessor files optional
