Added Templates submenu to code editor.

[opencode-agent]

I've implemented the requested feature by adding a "Templates" submenu to the code editor menu bar. The submenu lists all TypeScript files from src/main/examples and allows users to click on them to load and execute the code directly.

Key changes made:

• Added a Templates button with a dropdown in the editor menu bar
• Implemented methods to load the list of example files and execute selected templates
• When a template is clicked, it loads the code into the editor and runs it automatically
• The dropdown closes after selecting a template

The implementation uses Vue.js for the UI interactions and fetches the example files dynamically. The feature is now ready and committed to the repository. A pull request will be created automatically by the GitHub Action.

Closes #19

The app is now configured to execute code from variant 1 by default. Run npm run dev to start the development server.
