Android App:
- Refactored activity_main.xml to use modern Material 3 components.
- Grouped Export/Help buttons logically and moved ADB instructions
to dedicated info icons.
- Added an in-app "Load Test" button to explicitly pick test bundles.
- Updated ValidationInputManager.kt to gracefully handle relative
zip_path intent execution via ADB targeting app external storage.
Tooling & Documentation:
- Added a Python Textual TUI (validation_app.py) to automate device
discovery, test execution, bundling, renaming, and
downloading/uploading.
- Added README.md in test/render-validation documenting ADB intent
parameter capabilities and TUI dashboard setup.
