Add cxyz Android project structure and initial configuration

- Introduced a new Flutter project for the cxyz Android manga/comic reader, including essential files such as pubspec.yaml, AndroidManifest.xml, and Gradle configuration. - Added .gitignore files to exclude unnecessary files and directories for both the main project and Android-specific files. - Implemented initial README.md with project description, features, setup instructions, and API details for ComicLand, MangaRead, and MangaTown. - Configured analysis options and dependencies in pubspec.yaml to support Flutter development. - Established a pnpm workspace and lockfile for dependency management. - Included various Android resources such as icons, styles, and launch backgrounds for a complete application setup.
