* Warn on non-null assertions
- Surface non-null assertions during linting without making them blocking.
- Preserve existing assertion sites for opportunistic cleanup.
* Classify internal compiler errors
- Export InternalCompilerError and migrate compiler invariant throws without changing messages.
- Rename the native cache test to match cc.ts and update test scheduling references.
- Document test placement by unit, package integration, and cross-package scope.
* Fix internal compiler error classification
* Restore sandbox test performance
- Re-enable secure native compiler caching for repo-local test artifacts.
- Isolate strict cache coverage while keeping it off the sandbox critical path.
* fix: respect sandbox test runtime limits
