Enhance .gitignore, update dependencies, and improve CLI functionality

- Expanded .gitignore to include additional build outputs, environment files, and IDE configurations.
- Updated bun.lock to include new dependencies: js-yaml and its types.
- Refactored index.ts to export new validation functions and types for better modularity.
- Updated package.json to reflect version bump to 1.0.3, added repository and homepage information, and improved script commands.
- Enhanced README.md with clearer usage instructions and examples for library and CLI usage.
- Improved CLI commands for validation, parsing, and reporting, including support for multiple sources and detailed output options.
- Added logging functionality throughout the codebase for better debugging and user feedback.
- Implemented recursive validation and reference analysis features for comprehensive OpenAPI specification validation.
