- Rebuild StudioBridge-2.1.3.jar from latest upstream (v2.1.3) and deploy to portable-dist
- Add ensurePersistentDirectories() so the app creates ~/.studio-bridge and Profiles at startup (GUI + --sendonly)
- Bundle full StudioBridge source under StudioBridge-src/ (with rebuild-jar.bat)
- Update launchers (Launch-StudioBridge.bat, portable-dist/StudioBridge.bat) to v2.1.3
- Add check-update.ps1 and UPDATE.md for the step-by-step update runbook
- Update README (v2.1.3, persistent data + updating sections)
- Ignore StudioBridge-src/target/ build output
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.
