* 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
