Address review: ppp=1, local=true, Category filters

Align with nunit-browserstack (Selenium) sample conventions:
- browserstack.yml: parallelsPerPlatform 2 -> 1, browserstackLocal false -> true
- Tag fixtures with [Category("sample-test")] / [Category("sample-local-test")]
  so `dotnet test --filter "Category=..."` scopes the run (matches
  nunit-browserstack/SampleTest.cs and SampleLocalTest.cs)
- README: swap FullyQualifiedName filters for Category= filters; drop the
  now-redundant "flip the toggle" step; update parallelism narrative to ppp=1
  (4 platforms x 1 x 2 NUnit-parallel fixtures = still 8 concurrent sessions)
