refactor: remove github build variant

- Remove github build variant from build.gradle
- Keep only debug and release variants
- Update CI/CD workflows to remove github variant references
- Update documentation in CLAUDE.md
- Debug variant uses default Android debug signing
- Release variant uses keystore from KEYSTORE_BASE64 secret

Simplifies the build configuration by removing unnecessary variant.
