#788: Add support for IDE_OPTIONS variable per IDE commandlet

[Ali-Shariati-Najafabadi]

This PR fixes #788

Implemented changes:

• Added support for «IDE»_OPTIONS (e.g. INTELLIJ_OPTIONS, ECLIPSE_OPTIONS, VSCODE_OPTIONS, ANDROID_STUDIO_OPTIONS, PYCHARM_OPTIONS) to pass additional command-line arguments when starting an IDE, analogue to the existing global IDE_OPTIONS
• Implemented once in IdeToolCommandlet.runTool(List<String>) so it applies to all IDE commandlets (Eclipse, IntelliJ, Android Studio, PyCharm, VSCode/VSCodium) without per-tool duplication
• Scoped to only the actual IDE-launch call, not internal calls like plugin installation or repository import
• Registered the new variables in IdeVariables.java and documented them in variables.adoc

Testing instructions

1. Set e.g. INTELLIJ_OPTIONS=nosplash in conf/ide.properties
2. Run ide intellij and verify the extra argument is passed to the IDE binary
3. Automated coverage: mvn -Dtest=EclipseTest,IntellijTest,VscodeTest test in the cli module
