feat(editor): display clickable link when starting editor

[josephinecr]

What does this PR do?

This PR resolves issue #175 by explicitly displaying a clickable link in the terminal when the nf editor command is run.

Key changes:

• Extracted the URL generation logic from the openEditor method to the main handle method.
• Added a console output to display the generated link (with cyan formatting for visibility).
• This ensures that users always see the editor link in their terminal, which is especially useful if they run the command with the --no-open flag or if the automatic browser launch fails.

Closes #175

How do you test this PR?

1. Build the CLI (pnpm run build).
2. Run nf editor or nf editor --no-open.
3. Verify that the terminal logs 🔗 Editor running! Open it in your browser: http://localhost:3000/load-project...
4. Click the link to ensure it properly targets the editor.
