Add JRE auto-download to launcher

Browse Source 
Launch-StudioBridge.bat now checks for portable-dist\jre\bin\java.exe
on startup. If missing (e.g. fresh clone), it automatically downloads
Temurin 21.0.11+10 LTS JRE for Windows x64 (~47 MB) from GitHub and
extracts it into portable-dist\jre\ before starting StudioBridge.
