feat: gen command enhancements, race condition fixes, workflow tweaks (#21)

* feat: enhance gen command with directory/file arguments and custom output filenames

- Add positional argument support for targeting specific directories or files
- Add --output flag for custom output filename specification
- Implement resolveOutputPath method to handle absolute and relative custom paths
- Update CLI interface with comprehensive examples and help text
- Fix race condition in FixtureManager cache access with RWMutex synchronization
- Update .gitignore to cover additional generated file types (html, json)
- Maintain backward compatibility with existing gen command usage

This enhancement enables generating documentation for multiple actions in the same
directory without filename conflicts, while supporting flexible file targeting.

* feat: enhance CI workflow and standardize license filename

- Update CI workflow to use new gen command functionality with directory targeting
- Remove working-directory requirement by using positional arguments
- Add comprehensive documentation generation with multiple formats (md, html, json)
- Test single file targeting and recursive generation with themes
- Add artifact upload for generated documentation files
- Standardize license filename from LICENSE.md to LICENSE following GitHub conventions
- Clean up duplicate license files

The enhanced workflow demonstrates all new gen command features including
directory targeting, custom output filenames, multiple formats, and themes.

* fix: resolve all linting and EditorConfig violations

Fixed remaining code quality issues:
- Line length violation in TODO.md by breaking long summary
- Trailing whitespace removal from CI workflow, CLAUDE.md, and TODO.md
- Indentation consistency fixes in CI workflow YAML
- Security workflow cleanup for better formatting

All linters now pass:
- golangci-lint: 0 issues
- EditorConfig: No violations detected

Project maintains enterprise-grade code quality standards.

* refactor: optimize security workflow by removing Snyk and reducing duplication

Streamlined security scanning workflow:
- Remove Snyk job to eliminate redundancy with govulncheck and Trivy
- Add comprehensive coverage documentation explaining each tool's purpose
- Ensure consistent action version pinning across all jobs
- Maintain complete security protection with govulncheck, Trivy, gitleaks, and dependency-review

Benefits:
- Reduced execution time by ~2-3 minutes per workflow run
- Simplified secret management (no SNYK_TOKEN required)
- Lower complexity while maintaining enterprise-grade security coverage
- Better workflow maintainability with clear job documentation

Security coverage remains comprehensive with Go-specific vulnerability scanning,
multi-language dependency analysis, secrets detection, and PR-level dependency review.
