feat(docs): add CI/CD workflow testing documentation

Add test documentation to validate the CI/CD workflows are
functioning correctly. This PR will test:

- Branch name validation (feature/* pattern)
- PR title validation (Conventional Commits)
- Quality gates (Markdown linting, secret scanning)
- pr-into-dev.yml workflow execution

This is a test PR to ensure all GitHub Actions workflows
are properly configured and executing as expected.

+# CI/CD Workflow Testing
+
+This file validates that the ClaudeForge CI/CD system is working correctly.
+
+## Test Validation
+
+✅ **Feature Branch Created**: `feature/test-ci-workflow`
+✅ **Conventional Commits**: Testing commit message format
+✅ **Quality Gates**: Python, Markdown, Bash, Secret scanning
+✅ **PR Workflow**: pr-into-dev.yml should trigger
+
+## Expected Workflow Behavior
+
+When this PR is created targeting `dev`:
+
+1. **Branch Name Validation**: ✅ feature/test-ci-workflow (valid)
+2. **PR Title Validation**: Should follow `feat(docs): description` format
+3. **Quality Gates**:
+   - Python syntax validation (skip if no .py changes)
+   - Markdown linting (✅ this file should validate)
+   - Bash validation (skip if no .sh changes)
+   - Secret scanning (✅ should pass)
+4. **Fork Safety**: Not a fork, write operations allowed
+5. **Rate Limit**: Should have sufficient API calls
+
+## Success Criteria
+
+- [x] Feature branch created from dev
+- [ ] Committed with Conventional Commits format
+- [ ] Pushed to GitHub
+- [ ] PR created to dev
+- [ ] pr-into-dev.yml workflow triggered
+- [ ] All quality gates passed
+- [ ] PR ready for merge (testing only, will not merge)
+
+## Cleanup
+
+After validation:
+- Delete feature branch
+- Close PR without merging
+- Document any issues found
