chore(deps): update packages to their latest releases

[glennawatson]

What kind of change does this PR introduce?

Build / dependency maintenance.

What is the new behavior?

Every centrally managed package moves to its latest release, except the Roslyn pins that decide which compilers can load the shipped generator.

• Runtime and platform dependencies move up.
  • MAUI net10 heads go to 10.0.100.
  • ReactiveUI goes to 24.2.0, ReactiveUI.Primitives and ReactiveUI.Primitives.Reactive to 7.3.0.
• The analyzer set moves to its current baseline.
  • StyleSharp, PerformanceSharp and SecuritySharp go to 3.46.0.
  • Roslynator goes to 5.0.0 and the C# quality analyzer to 10.33.0.1635.
  • No new diagnostics fire, so no source changes were needed.
• The test stack moves to TUnit 1.66.8 and Verify.TUnit 32.0.0. Verify 32 accepts the existing snapshots unchanged; no .verified.cs file moves.

What is the current behavior?

The pins predate these releases: MAUI 10.0.90, ReactiveUI 24.1.0, ReactiveUI.Primitives 7.2.0, the 3.45.0 analyzer baseline, Roslynator 4.16.1, TUnit 1.65.0 and Verify.TUnit 31.28.0.

What might this PR break?

None expected.

• Roslynator and Verify.TUnit each cross a major version. Neither changes anything here, but both are the kind of bump worth knowing about when reading a later failure.
• Microsoft.CodeAnalysis.CSharp and .Workspaces deliberately stay on 4.14.0, with the shipping generator and analyzer projects still overriding to 4.8.0. That floor is what lets the .NET 8 SDK and Visual Studio 2022 17.8 load the analyzers at all; raising it would drop those consumers.
