PackageFix
Fixed security setting not persisting after editor restart. (UUM-150249) First seen in 6000.7.0a5.
Fixed signed packages from scoped registries incorrectly reporting an unchecked signature status. The _fingerprint package manifest property is reserved and only valid when read from the installed package folder, where it is injected at installation; it is now stripped when reading a package manifest from any other source (such as registry package metadata) so a wrong value cannot be used in place of the computed/injected one.

Measure.Method().GC() again forces a full garbage collection immediately before each timed region, restoring the behavior from before the switch to the ProfilerRecorder API. Without it, a collection triggered by the measured code's own allocations lands inside the timed region and shows up as periodic spikes across the samples. As before: this only happens when GC() is specified; warmup and probing iterations are not affected; and because SetUp/CleanUp cause each of the IterationsPerMeasurement inner executions to be timed separately, that combination gets one collection per inner execution rather than one per sample, which makes it considerably slower. Reported times for allocating methods measured with GC() will change, generally becoming lower and more stable, so baselines recorded since 3.2.1 are not comparable.
