feat(commands): add GitHub workflow integration slash commands

Phase 4: Claude Code Slash Commands

Created 4 GitHub Integration Commands:

1. /github-init - CI/CD system initialization
   - Runs bootstrap workflow
   - Creates dev branch
   - Configures branch protection
   - Sets default branch to dev
   - Complete setup verification

2. /commit-smart - Smart commits with quality gates
   - Pre-commit validation (Python, Bash, secrets)
   - Conventional Commits format generation
   - Interactive commit message builder
   - Quality checks before committing

3. /create-pr - Pull request creation
   - Branch validation
   - Target branch detection (dev/main)
   - PR title generation (Conventional Commits)
   - PR template population
   - Workflow trigger explanation

4. /release - GitHub release creation
   - Version validation (semantic versioning)
   - CHANGELOG.md integration
   - Automated release notes
   - Post-release actions guide

All commands provide:
- Step-by-step guidance
- Copy-paste ready commands
- Validation checks
- Error handling
- Links to documentation

Integration with workflows:
- Commands trigger bootstrap, pr-into-dev, dev-to-main, release workflows
- Enforces quality gates and conventions
- Aligns with branching strategy

Next: Test workflows with sample feature PR

+# GitHub CI/CD Initialization
+
+You are helping the user initialize the ClaudeForge CI/CD system.
+
+## Workflow
+
+1. **Check Current State**
+   - Verify `.github/workflows/` directory exists
+   - Check if bootstrap workflow has been run (look for labels/milestones)
+   - Check if dev branch exists
+   - Check branch protection status
+
+2. **Run Bootstrap Workflow**
+   - If not yet run, guide user to run bootstrap workflow:
+     - Go to Actions → Bootstrap Repository → Run workflow
+     - Enable all options (create labels, milestones, validate settings)
+   - Explain what will be created (23 labels, 3 milestones)
+
+3. **Create Dev Branch** (if not exists)
+   ```bash
+   git checkout -b dev
+   git push -u origin dev
+   ```
+
+4. **Configure Branch Protection**
+
+   Guide user step-by-step:
+
+   **For main branch:**
+   - Go to Settings → Branches → Add rule
+   - Pattern: `main`
+   - Enable:
+     - Require PR before merging
+     - Require status checks: `quality-gates`, `production-build`, `validate-release-pr`
+     - Require linear history
+     - Block force pushes
+     - Restrict deletions
+
+   **For dev branch:**
+   - Pattern: `dev`
+   - Enable:
+     - Require PR before merging
+     - Require status checks: `quality-gates`, `validate-pr`
+     - Require linear history
+     - Block force pushes
+     - Restrict deletions
+
+5. **Set Default Branch**
+   - Settings → General → Default branch → Change to `dev`
+   - This ensures new PRs target dev by default
+
+6. **Verification**
+   - Show current branch protection rules
+   - Verify workflows are present
+   - Confirm setup is complete
+
+7. **Next Steps**
+   - Point to docs/GITHUB_WORKFLOWS.md for workflow reference
+   - Point to docs/BRANCHING_STRATEGY.md for branch flow
+   - Suggest creating first feature branch to test
+
+## Commands to provide
+
+```bash
+# Check current setup
+gh repo view --json name,defaultBranchRef,hasIssuesEnabled
+
+# List workflows
+ls -la .github/workflows/
+
+# Check labels
+gh label list
+
+# Check milestones
+gh api repos/:owner/:repo/milestones
+
+# Check branch protection
+gh api repos/:owner/:repo/branches/main/protection 2>/dev/null || echo "Not protected"
+gh api repos/:owner/:repo/branches/dev/protection 2>/dev/null || echo "Not protected"
+```
+
+## Success Criteria
+
+✅ Bootstrap workflow run successfully
+✅ Dev branch created and pushed
+✅ Branch protection configured for main and dev
+✅ Default branch set to dev
+✅ User understands next steps
+
+Provide clear, step-by-step guidance with actual commands the user can copy-paste.
