Ludy 1ded9abb46 build(tauri): enforce Java 17+ requirement in Windows jlink build script (#5684)
# Description of Changes

This pull request improves the `scripts/build-tauri-jlink.bat` build
script by adding a check to ensure that Java 17 or higher is installed
before proceeding. This helps prevent build errors due to incompatible
Java versions.

Build process enhancements:

* Added logic to parse the installed Java version and verify that it is
at least version 17; the script now exits with an error message if an
older version is detected.
* Updated status messages to clearly indicate the Java version being
used and to provide feedback if requirements are not met.

echo.
echo 📋 Next steps:
echo 1. cd frontend
echo 2. npm run tauri-build
echo.
echo 💡 Testing:
echo • Test bundled runtime: frontend\src-tauri\runtime\launch-stirling.bat
echo • Tauri configuration already updated to include bundled JRE
echo.
echo 💡 Benefits:
echo • No external JRE dependency
echo • Smaller distribution size with custom runtime
echo • Better security with minimal required modules
echo • Consistent Java version across all deployments
echo.
echo ✅ The application will now run without requiring users to install Java!
