/upgrade — Project Configuration Upgrade

Upgrades your .NET project to the latest C# standards configuration.

What This Does

Compares your project's configuration files with the latest templates and offers to update them:

Usage

Copy/upgrade              # Check and upgrade all files
/upgrade --check      # Only show what's outdated (no changes)
/upgrade --force      # Replace all files without asking

Workflow

1. Scan — Find existing config files
2. Compare — Check against latest templates
3. Report — Show what's missing/outdated
4. Confirm — Ask what to update
5. Apply — Make changes
6. Verify — Run dotnet restore && dotnet build

Example Output
