## Detailed Description of the Pull Request / Additional comments
I added a new file, `Commands/UninstallApplicationCommand.cs`, which
implements the logic to uninstall applications directly from the Command
Palette. The command differentiates between UWP apps and Win32 programs.
All common error scenarios are properly handled and logged to ensure
reliability and traceability.

Additionally, in `Icons.cs`, I included the "Delete" icon from the
Windows Start menu to be displayed alongside the uninstall commands in
the Command List, providing a familiar visual cue for users.

The uninstall commands have been integrated into the appropriate classes
for both UWP and Win32 applications, making them fully accessible and
consistent across the Command Palette.
The command can be triggered using the shortcut Ctrl + Shift + Delete
for quick access.

<!-- Describe how you validated the behavior. Add automated tests
wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Tested locally; currently, verification was limited to uninstalling a
UWP application, unsure of additional test scenarios.

*Note: This is my first PR draft, so apologies if I missed anything.*
