Comprehensive CI/CD Implementation - COMPLETE ✅

All requirements from the issue have been successfully implemented:

✅ Completed Requirements

1. Comprehensive CI/CD Pipeline

• ✅ PR validation workflow runs on all pull requests
• ✅ Release workflow runs on merges to main/master
• ✅ Both workflows run tests and CodeQL security scanning

2. GitHub Releases with Runtime

• ✅ Self-contained .NET runtime builds for 6 platforms:
  • Linux (x64, ARM64)
  • Windows (x64, ARM64)
  • macOS (x64, ARM64)
• ✅ Both Debug and Release builds included
• ✅ All dependencies shipped with runtime (self-contained)

3. Automated Testing & Security

• ✅ Tests run on PRs and main branch (continues gracefully if no tests exist)
• ✅ CodeQL security scanning on PRs
• ✅ CodeQL security scanning on main branch merges

4. Automatic Versioning

• ✅ GitVersion configuration using SemVer
• ✅ Automatic version updates based on git tags
• ✅ Assembly versions automatically updated during build
• ✅ Version info embedded in all published binaries

5. Automatic Release Notes

• ✅ Release notes generated from git commit history
• ✅ Includes list of changes since last tag
• ✅ Platform support information included

📁 Files Added/Modified

New Files:

• GitVersion.yml - GitVersion configuration for semantic versioning
• .github/workflows/pr-validation.yml - PR validation with build, test, and CodeQL
• .github/workflows/release.yml - Release workflow with versioning and publishing

Modified Files:

• src/Cryogenic/Cryogenic.csproj - Added version properties for GitVersion

Removed Files:

• .github/workflows/autorelease.yml - Replaced by comprehensive release.yml

🔧 How It Works

On Pull Requests:

1. PR validation workflow triggers automatically
2. GitVersion calculates version from branch
3. Project builds with versioned assemblies
4. Tests run (gracefully continues if none exist)
5. CodeQL performs security analysis
6. PR checks pass/fail based on results

On Merge to Main:

1. Release workflow triggers automatically
2. GitVersion calculates release version
3. Build, test, and CodeQL scan run
4. Multi-platform binaries published with embedded versions
5. Release notes generated from git commits
6. GitHub release created with version tag (e.g., v0.1.1)
7. Distribution packages attached to release

🏷️ Versioning Strategy

• main/master branch: Patch increment (e.g., 0.1.0 → 0.1.1)
• develop branch: Minor increment with alpha tag (e.g., 0.2.0-alpha.1)
• feature branches: Branch name tag (e.g., 0.1.1-feature-name.1)
• pull requests: PR tag (e.g., 0.1.1-PullRequest0001.1)
• release branches: Beta tag (e.g., 1.0.0-beta.1)
• hotfix branches: Patch increment with beta tag

✅ Validation Complete

• ✅ Project builds successfully with version properties
• ✅ YAML workflows are valid and properly formatted
• ✅ CodeQL security scan passed with 0 alerts
• ✅ Version information correctly embedded in assemblies
• ✅ All workflow permissions properly configured

🚀 Next Steps

The CI/CD pipeline is ready to use:

1. This PR will trigger the PR validation workflow
2. Once merged to main, the release workflow will create the first versioned release
3. Future PRs will automatically validate with tests and security scans
4. Future merges to main will create new releases with incremented versions

• Fixes comprehensive CI/CD #46
