rename app module to jrunner for consistency

Changes:
- Rename app/ directory to jrunner/ (preserves git history)
- Update settings.gradle to reference jrunner module
- Update readme.md with new paths (jrunner/build/, /opt/jrunner)
- Update CLAUDE.md documentation with new file paths

Build outputs now named jrunner.zip, jrunner.jar, bin/jrunner instead
of generic "app" names. This makes the project structure clearer and
aligns module name with project name.

 ### Single-File Design
-The entire application logic resides in `app/src/main/java/jrunner/jrunner.java`. This is a monolithic command-line tool with no abstraction layers or separate modules.
