Remove placeholder Button.js file from test-app root directory

[Copilot]

Problem

The file test-app/Button.js was a placeholder file containing dummy content that was accidentally committed to the repository. This file included comments indicating it was not the actual implementation:

// Original content of Button.js before any changes were made

// Assuming this is how the original file looked. You need to provide the actual original content here.

export default class Button {
    constructor(label) {
        this.label = label;
    }

    render() {
        // Logic to render the button with this.label
    }
}

Solution

Removed the placeholder file from test-app/Button.js as it serves no purpose and can cause confusion.

Why This is Safe

The actual Button component implementation exists at test-app/src/widgets/Button.js (110 lines, fully functional) and is properly used throughout the codebase. All imports reference the widget correctly:

import Button from './Button';  // From within test-app/src/widgets/

These relative imports resolve to test-app/src/widgets/Button.js, not the root-level placeholder file. Removing the placeholder has no impact on functionality.

Files Changed

• Deleted: test-app/Button.js (placeholder/dummy file)
