chore: update NuGet packages — Copilot SDK + MAUI 10.0.60 + all others

[PureWeen]

Update all NuGet dependencies to latest stable versions, specifically:

Required updates

• GitHub.Copilot.SDK — update to latest available (currently on 0.2.2). If there are breaking API changes, fix them.
• Microsoft.Maui.* packages — update to 10.0.60 or latest preview.6+
• MauiDevFlow packages — update if preview.6+ is available
• All other packages — update to latest stable

Process

1. Run dotnet outdated or check each csproj for updatable packages
2. Update all package references across: PolyPilot/, PolyPilot.Gtk/, PolyPilot.Tests/, PolyPilot.IntegrationTests/, PolyPilot.Console/, PolyPilot.Provider.Sample/, Directory.Build.props
3. Fix any breaking API changes from the SDK update
4. Run all tests and fix failures
5. Build Mac Catalyst and Windows to verify no build breaks

Notes

• If GitHub.Copilot.SDK has breaking changes (removed/renamed types), fix the call sites rather than skipping the update
• Check nuget.config for any source changes needed
• Previous update (chore: update NuGet dependencies #772) skipped SDK 0.3.0 due to breaking changes — this time we want to take the update and fix whatever breaks
