session-studio: runnable jar — shadow fat jar + module-path launcher + wrapper script

- Launcher.java: non-Application Main-Class entry point (bypasses JVM Application subclass check)
- build.gradle: shadow plugin 8.1.1 for fat jar; startScripts patched with --module-path \$APP_HOME/lib + --add-modules; generateWrapper task writes project-root ./ac-session-studio script
- ac-session-studio: generated launcher wrapper (./ac-session-studio to run)

java -jar build/libs/ac-session-studio.jar still requires --module-path; use ./ac-session-studio instead
