Description

Updates the WinApp CLI banner from the existing blue-to-purple palette to a Windows/WinUI-inspired light-blue-to-deep-blue gradient. The palette includes the Microsoft blue accent (#0078D4) and uses true-color ANSI sequences in supported terminals.

Usage Example

winapp

The banner now transitions through #60CDFF, #3CB4FF, #0099FF, #0078D4, and #005A9E.

Related Issue

None.

Type of Change

• 🧪 Test update

Checklist

• New tests added for new functionality
• Tested locally on Windows

Screenshots / Demo

Run winapp in Windows Terminal or the VS Code terminal to see the updated gradient.

Additional Notes

BannerHelperTests passes all 10 focused tests. The full repository build was also attempted; it progressed into the broader test suites but could not complete because the local machine ran out of disk space and encountered unrelated ARM64/environment-dependent test failures.
