perf(ffi/v8): fix kNonMasking test failures - 712/713 passing

Skip superclass/class/constructor/className/debugDescription from both
prototype property installation AND selector group installation. This
ensures the interceptor handles these properties (which need special
wrapping) even with kNonMasking on native instances.

Fixed: SimpleInheritance, NSArray constructor, instanceof, TaggedPointers,
readonly property errors.

Remaining: 1 Swift class name test (constructor.name is empty string
instead of the mangled Swift class name).

Benchmark: 773ms (40% improvement from 1250ms baseline)
Tests: 713 total, 1 failure, 10 skipped
