Gate Perception suppression to debug

[johnnewman-square]

This PR builds on the changes from #389.

Summary

• gate skipPerceptionChecking behind #if DEBUG via a shared helper
• apply the debug-only suppression to both readState and child-wrapper access(...)
• add test_nativeOptionalChildStoreObservation so native observation covers the wrapper path through Store.access(...)
• include the updated Samples/Tuist/Package.resolved

Why

Perception only consults skipPerceptionChecking from its debug-only checking path, so release builds do not need the TaskLocal wrapper. The new native optional-wrapper test closes the coverage gap in the path that motivated the original suppression.

Test plan

• Ensure the new test passes
• Look for regressions on the ObservableComposition app.
