Abdessamad Derraz 58f3006d20 docs: add core_version, display_name to all 260 emulator profiles
Every profile now has:
- profiled_date: date of source code analysis
- core_version: version from libretro-core-info .info files
- display_name: human-readable name from .info files

260/260 profiles complete. 294/294 libretro cores covered.
Standalone emulators (cemu, rpcs3, xemu, vita3k) versioned manually.

notes: |
Fork of the final open-source redream release (pre-relicense). Experimental
core with no HLE BIOS -- real BIOS files are required to boot games.
Flycast is recommended over this core for actual gameplay.
The libretro core sets appdir to the RetroArch system directory
(src/host/retro_host.c:216-217). boot.bin and flash.bin are loaded
directly from appdir (src/guest/rom/boot.c:17, src/guest/rom/flash.c:30).
The .info file declares paths as dc/boot.bin and dc/flash.bin, which means
RetroArch resolves them under {system_dir}/dc/.
boot.bin is validated against four known MD5 hashes at load time
(src/guest/rom/boot.c:25-30). If validation fails, the core logs a warning
but still attempts to run via HLE syscall hooks (bios.c:440-447).
flash.bin is read/write -- the core saves modified flash data back to disk
on shutdown (src/guest/rom/flash.c:197-199).
Boot ROM size: 2 MB (0x200000). Flash ROM size: 128 KB (0x20000).
