Expand capability tests: cover tuning, compile, and multi-capability dispatch Add positive 'queryable and usable' tests for ITuningCapability (call-counted routing) and ICompileCapability (Compile + ValidateCompiledModelCompatibilityInfo), a multi-capability EP test verifying correct mix-in dispatch under multiple inheritance, and compile-null independence checks. 7 tests pass.
