Abdessamad Derraz 8458e92281 chore: advance 135 profile pins to upstream HEAD
Every cited block was read again at HEAD: no ref left to review, no
file name or hash literal added to a cited file since the pin
(--detect-new-files --watch-hashes), refs recaled with their pins.
Profiles built by a platform at a fixed commit, or whose bump would
leave prose under an older pin, stay where they were.

notes: |
The native core is a C bridge that spawns a Java process running
freej2me-lr.jar, which handles all J2ME emulation. Communication
happens over pipes (Linux) or named pipes (Windows). A Java runtime
(JRE/JDK 8+) must be installed on the host. The jar is built from
source via Apache Ant (build.xml). Same repo hosts standalone AWT
and SDL2 frontends alongside the libretro frontend.

note: "Not a BIOS dump. Java emulator loaded by the native core at startup via execvp('java', '-jar', path). Built from source via 'ant'. Must be in the system directory root. ROCKNIX builds the core and the jar from freej2me-plus 1.52, which keeps the freej2me-lr.jar name, and copies the jar into its BIOS folder before each launch when it is missing."
