feat: add ReTrace mapping file upload to Google Play Console

[graycreate]

Summary

Enable automatic upload of ProGuard/R8 mapping files to Google Play Console for crash deobfuscation.

Changes Made

Release Workflow (.github/workflows/release.yml)

• ✅ Bundle Artifact: Include mapping.txt in release-bundle artifact alongside AAB file
• ✅ File Detection: Add mapping file discovery in Find bundle and symbols step
• ✅ Upload Configuration: Add mappingFile parameter to both Google Play upload steps

Workflow Logic

# Package mapping file with AAB
path: |
  app/build/outputs/bundle/**/*.aab
  app/build/outputs/mapping/release/mapping.txt

# Detect mapping file
MAPPING_PATH=$(find release-artifacts -name "mapping.txt" 2>/dev/null | head -1)

# Upload to Google Play Console
mappingFile: ${{ steps.find-files.outputs.mapping_path }}

Benefits

🎯 Crash Deobfuscation: Stack traces in Google Play Console will show original class/method names
📊 Better Debugging: Production crashes can be properly diagnosed with unobfuscated stack traces
🔄 Automatic Process: No manual mapping file upload required
✅ Backwards Compatible: Works whether mapping file is present or not

Impact

• Next Release: Will automatically upload ReTrace mapping file to Google Play Console
• Crash Reports: Production crash stack traces will be properly deobfuscated
• Security: App remains obfuscated while maintaining debuggability

Dependencies

This PR builds on the minification changes in PR #91:

• Requires R8 minification to be enabled (minifyEnabled true)
• Depends on mapping.txt file generation during build process

Pull Request Overview

This PR enables automatic upload of ProGuard/R8 mapping files to Google Play Console to enable crash deobfuscation, allowing production crash stack traces to display original class and method names instead of obfuscated ones.

• Modifies the release workflow to include mapping.txt files in the release bundle artifact
• Adds discovery logic to detect ProGuard/R8 mapping files in the downloaded artifacts
• Configures both Google Play upload steps to include the mapping file parameter

The mapping file path is hardcoded to the release build variant. Consider using a wildcard pattern like app/build/outputs/mapping/**/mapping.txt to support different build variants and configurations.
