feat: extract version bump logic into reusable script (#140)

# Extract Version Bump Logic into Reusable Script This PR extracts the version bump logic from the GitHub Actions workflow (PR #137) into a reusable script and implements the requirements as requested. ## ✅ What This PR Delivers ### 🔧 **Version Bump Script**: `.github/scripts/version-bump.sh` - Extracts all version bump logic from the original workflow - Supports `patch`, `minor`, and `major` version bumps - Configurable base reference for diff comparison (defaults to `origin/main`) - Comprehensive error handling and semantic version validation - Can be used standalone or in workflows ### 🔍 **Version Check Workflow**: `.github/workflows/version-check.yaml` - **Required CI check** that runs on all PRs modifying modules - Verifies that module versions have been properly updated - Fails if versions need bumping but haven't been updated - Provides clear instructions on how to fix version issues ### 🚀 **Version Bump Workflow**: `.github/workflows/version-bump.yaml` - Simplified workflow that uses the extracted script - Triggered by PR labels (`version:patch`, `version:minor`, `version:major`) - Automatically commits version updates and comments on PR ### 📚 **Updated Documentation**: `CONTRIBUTING.md` - Clear instructions on how to use the version bump script - Examples for different bump types - Information about PR labels as an alternative - Explains that CI will check version updates ## 🎯 Key Features ✅ **Script Logic Extracted**: All complex bash logic moved from workflow to reusable script ✅ **Required CI Check**: Version check workflow ensures versions are updated ✅ **Diff Verification**: Script checks git diff to detect modified modules ✅ **Contribution Docs Updated**: Clear instructions for contributors ✅ **Backward Compatible**: Maintains all original functionality ✅ **Error Handling**: Comprehensive validation and clear error messages ## 📖 Usage Examples ```bash # For bug fixes ./.github/scripts/version-bump.sh patch # For new features ./.github/scripts/version-bump.sh minor # For breaking changes ./.github/scripts/version-bump.sh major ``` ## 🔄 Workflow Integration 1. **Developer makes changes** to modules 2. **CI runs version-check** workflow automatically 3. **If versions need updating**, CI fails with instructions 4. **Developer runs script** or adds PR label 5. **Versions get updated** automatically 6. **CI passes** and PR can be merged ## 🧪 Testing The script has been tested with: - ✅ Valid and invalid bump types - ✅ Module detection from git diff - ✅ Version calculation and validation - ✅ README version updates - ✅ Error handling for edge cases This implementation addresses all the original requirements while making the logic more maintainable and reusable. --------- Co-authored-by: blink-so[bot] <211532188+blink-so[bot]@users.noreply.github.com> Co-authored-by: DevelopmentCats <christofer@coder.com>

 ## Versioning Guidelines

-After your PR is merged, maintainers will handle the release. Understanding version numbers helps you describe the impact of your changes:
+When you modify a module, you need to update its version number in the README. Understanding version numbers helps you describe the impact of your changes:

 - **Patch** (1.2.3 → 1.2.4): Bug fixes
 - **Minor** (1.2.3 → 1.3.0): New features, adding inputs
 - **Major** (1.2.3 → 2.0.0): Breaking changes (removing inputs, changing types)

-**Important**: Always specify the version change in your PR (e.g., `v1.2.3 → v1.2.4`). This helps maintainers create the correct release tag.
+### Updating Module Versions
+
+If your changes require a version bump, use the version bump script:
+
+```bash
+# For bug fixes
+./.github/scripts/version-bump.sh patch
+
+# For new features
+./.github/scripts/version-bump.sh minor
+
+# For breaking changes
+./.github/scripts/version-bump.sh major
+```
+
+The script will:
+
+1. Detect which modules you've modified
+2. Calculate the new version number
+3. Update all version references in the module's README
+4. Show you a summary of changes
+
+**Important**: Only run the version bump script if your changes require a new release. Documentation-only changes don't need version updates.
