What's new in this PR?

Issues

the current pipeline is hard to extend or change, and a lot of the stuff are not clearly visible

Solutions

Pipeline Architecture

• Old System: Separate workflow files for each branch/environment
• New System: Unified workflow with reusable components and matrix builds

Workflow Mapping

Key Improvements

1. Unified Architecture

• Single base workflow: build-unified.yml handles all build logic
• Reusable components: quality-gates.yml, deploy.yml
• Consistent behavior: Same build process across all environments

2. Matrix-Based Builds

• JSON configuration: Each trigger defines build matrix in JSON format
• Flexible combinations: Flavor, variant, keystore, and deployment targets
• Easy expansion: Add new build configurations without duplicating code

3. Enhanced Deployment

• Multi-target deployment: S3, Google Play, GitHub Releases in single workflow
• Automated internal testing: internal edge deployment is not automated for each push into develop
