feat: Implement Automated Android Build Pipeline

Implements a complete, two-stage GitHub Actions pipeline to automatically build an Android APK from the repository.

- **Configuration Bot**: A workflow (`config-bot.yml`) runs on every push to ensure the repository has a valid Android project structure. It executes a script (`align_android_config.sh`) to generate any missing Gradle files, source files, or the official Gradle Wrapper, and auto-commits the changes.
- **Build Bot**: A second workflow (`android-build.yml`) triggers after the configuration bot succeeds. It sets up a Java/Android environment, installs frontend dependencies for the web terminal (`npm install`), and builds a debug APK using Gradle.
- **Self-Contained APK**: The resulting Android application packages the web terminal and embeds a `nodejs-mobile-android` runtime. This allows the terminal's `server.js` backend to run directly on the device, making the application fully self-contained and functional. The `server.js` and Android runtime logic have been aligned to work together correctly.
- The final APK is uploaded as a downloadable artifact from the GitHub Actions run.
