The mutate list below MUST mirror KERNEL_MODULES in scripts/mutation/modules.ts — scripts/mutation/config.test.ts asserts it. The lane reports scores and never gates on them (#1457), so no `break` threshold may be set here either.

Stryker's sandbox rewrites tsconfig `extends`/`references` through the classic TypeScript API, which the repo's TypeScript 7 native package no longer exposes (`ts.parseConfigFileTextToJson is not a function`). Our tsconfig has neither extends nor references, so there is nothing to rewrite — skipping the preprocessor is exact, not a workaround for a real dependency. The behaviour relied on is that the preprocessor no-ops when the file is absent: see packages/core/src/sandbox/ts-config-preprocessor.ts (https://github.com/stryker-mutator/stryker-js/blob/master/packages/core/src/sandbox/ts-config-preprocessor.ts) and https://stryker-mutator.io/docs/stryker-js/configuration/#tsconfigfile-string.
