Walkthrough

This PR adds Mattermost Windows desktop application support to Fleet's maintained apps system. It introduces a Winget input manifest defining Mattermost metadata (identifier, x64 architecture, MSI installer, machine-wide scope), registers the application in the apps catalog as mattermost/windows, and provides Windows-specific configuration including version 6.0.4 detection logic, MSI installer details with SHA256 integrity verification, and PowerShell scripts for automated installation via msiexec and uninstallation via upgrade code.
