chore: Update version to 3.1.1 and modify CLI entry point

- Bumped package version to 3.1.1 in package.json to match the new release.
- Changed the CLI entry point to use the new bin/openapi-mcp-generator.js file.
- Updated build script to ensure the new CLI file has the correct permissions.
- Refactored index.ts to streamline argument parsing and error handling.
