Subject: [PATCH] test(fork): add bUnit smoke test and fork CI workflow

Confirm bUnit works against the fork's stack (xUnit v3 + Microsoft.Testing.Platform
on net10/net11) by rendering UseFragment<T> and asserting ChildContent /
LoadingContent, and add a pull_request CI workflow scoped to the forked packages.

- add bunit 2.7.2 to central package management
- StrawberryShake.Razor.Tests references bunit; UseFragmentBunitTests renders the
  component via bUnit (4/4 pass on net10 and net11)
- ci-fork.yml builds + tests Razor.Tests (runtime + bUnit) and Core.Tests on
  pull_request and fork/release-branch pushes (the Razor codegen snapshot tests bake
  the generator assembly version and aren't CI-portable, so they are excluded)
