Abdessamad Derraz d929424988 feat: add profiled_date to all YAMLs, create 56 alias profiles
- Added profiled_date field to all 204 existing profiles for update tracking
- Created 56 alias profiles for cores that share BIOS with a parent
  (e.g., mednafen_psx -> beetle_psx, fbalpha2012 -> fbneo)

260 total profiles covering all 294 libretro cores (204 unique + 56 alias).

notes: |
FreeJ2ME is a Java ME (J2ME) emulator for libretro. The native .so/.dll
core acts as a bridge that spawns a Java process running freej2me-lr.jar,
which handles all actual J2ME emulation. Communication between the C
frontend and Java backend happens over pipes (Linux) or named pipes
(Windows).
The jar file is required: without it the core cannot start. It must be
placed directly in the system directory (not a subdirectory). The core
resolves it via RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY joined with
"freej2me-lr.jar" using fill_pathname_join().
A working Java runtime (JRE/JDK 8+) must be installed on the host
system. The core invokes "java -jar freej2me-lr.jar" with resolution,
rotation, phone type, FPS, and sound arguments passed via argv.
freej2me-lr.jar is built from the project source via Apache Ant
(build.xml target "lr"). It is not a traditional BIOS dump but a
software component distributed with the emulator.
The project also produces freej2me.jar (standalone AWT frontend) and
freej2me-sdl.jar (SDL2 frontend), but only freej2me-lr.jar is needed
for the libretro core.
