Makes TypeScript report an error where app code uses a feature that redact() turns off.

src/features/suspense.tsx(6,6): error TS2741: Property ''Redact: <Suspense> requires the `suspense` feature. Set `features.suspense: true` in redact().'' is missing in type '{ children: Element; fallback: Element; }' but required in type 'SuspenseProps'.

• redact() writes src/redact.gen.d.ts from the resolved feature flags. The file has one /// <reference types="@tanstack/redact/disabled/<feature>" /> line per disabled feature. It is rewritten only when its content changes. The new dts option sets another path or turns the file off. Without src/, the default file is skipped. A custom path whose directory is missing logs a warning.
• packages/redact/disabled/*.d.ts merge into @types/react and @types/react-dom. Declaration merging can only add, so each file makes the existing API unusable:
  • <Activity>, <Suspense>, context providers, and forwardRef() get a required never prop. The prop name is the error message.
  • lazy(), createPortal(), and hydrateRoot() get an overload that takes priority and returns an unusable type. The overload is also marked @deprecated.
  • Class lifecycles other than render, setState, and componentWillUnmount get conflicting overloads. A class that uses none of them still satisfies ComponentType.
  • memo() and addTransitionType() are only marked @deprecated, because turning them off changes performance or animation rather than behavior. fragmentRefs has no type check.
• @types/react and @types/react-dom are optional peer dependencies, so pnpm links the same copy the app uses.
• tests/feature-types.test.ts type-checks a fixture against @types/react 19.3 with skipLibCheck: false. Errors appear only on marked lines, enabled features add none, and the language service reports the expected deprecations.
• examples/feature-types turns off every feature and then uses each one. pnpm typecheck there reports 12 errors. ssr-demo sets dts: false because its tsconfig maps react to Redact's source.

Notes

The file is written by default, so every Vite project with a src/ folder gets one. With the full preset it only references viewTransitions. We may want to make it opt-in before release. Only the app's own source is checked. Compiled dependencies are not.
