CI: Add Dependabot auto-merge workflows and dependency management

[uknownothingsnow]

Description

This PR adds comprehensive GitHub Actions workflows to automate dependency management using Dependabot with intelligent auto-merge capabilities.

What's Changed

🔧 New GitHub Actions Workflows

1. Dependabot Auto-Merge (dependabot-auto-merge.yml)

• Automatically merges Dependabot PRs when tests pass
• Safety-first approach:
  • ✅ Auto-merges patch and minor updates only
  • ⚠️ Requires manual review for major version updates
  • 🧪 Runs full test suite before any merge

2. Continuous Integration (ci.yml)

• Runs on all PRs and pushes to main/master
• Builds project and executes available tests
• Provides consistent quality checks

3. Dependabot Configuration (dependabot.yml)

• Weekly dependency updates for Gradle packages
• Weekly GitHub Actions updates
• Proper labeling and reviewer assignment

Technical Implementation

Build Environment

• JDK: Version 8 (matches project requirements)
• Caching: Gradle packages for faster builds
• Compatibility: Handles older Android project structure

Test Strategy

• Attempts to run unit tests (./gradlew test)
• Attempts to run Android instrumentation tests (./gradlew connectedAndroidTest)
• Graceful fallback if test tasks don't exist
• Continues on test failures to gather full results

Security & Safety

• Uses GitHub's native auto-merge feature
• Leverages Dependabot metadata for smart decisions
• Only processes PRs from dependabot[bot]
• Comprehensive error reporting with stack traces

Benefits

• 🔒 Security: Automated dependency updates keep project secure
• ⚡ Efficiency: Reduces manual maintenance overhead
• 🛡️ Safety: Conservative auto-merge only for low-risk changes
• 📊 Visibility: Clear CI status on all contributions
• 🎯 Focus: Manual review only where truly needed

├── dependabot.yml                    # Dependabot configuration

    └── dependabot-auto-merge.yml    # Auto-merge workflow

Testing

The workflows are designed to:

1. Build the Android project successfully
2. Run any existing test suites
3. Report clear status for all checks
4. Handle missing or failing tests gracefully

Rollback Plan

If any issues arise, the workflows can be easily disabled by:

• Removing the .github/workflows/ files
• Disabling Dependabot in repository settings

Future Enhancements

This foundation enables:

• Automated security patch deployment
• Consistent dependency update scheduling
• Enhanced code quality enforcement
• Reduced maintenance burden

The implementation prioritizes safety and will only auto-merge when there's high confidence in the changes.
