TASK-021-005: Add HTTP/2 connection and multiplexing integration tests

- Created `src/TurboHttp.IntegrationTests/H2/ConnectionIntegrationTests.cs` with 5 tests
- Tests cover: sequential reuse, concurrent multiplexing (Task.WhenAll), binary POST echo, multi-endpoint, and POST+GET on same connection
- All tests use `[Collection("H2")]` and `new Version(2, 0)`
- DisplayNames follow `Conn-H2-001` through `Conn-H2-005` pattern
- Build: 0 errors, 0 warnings
- All 5 tests pass
