Updated monaco-editor-wrapper to the latest version (3.1.0), and the built-in example accordingly
Updated the built-in web-app to use the latest wrapper & langium versions, plus some freshening up
Reworked the CLI to directly output either an AST or generated drawing commands as JSON, more closely matching the language server's output on document validation
Reworked the old generate:test script (and dropped generate:logo) to just output the CLI's generated drawing commands to the console
Changed the package.json to use explicit exports, for ESM compatibility
