/**
 * Dev-only: reads the docs of the project's own components from each module
 * Vite transforms and keeps them in `index`, which the `componentDocs` node
 * action asks before any manifest. Changes no code.
 *
 * It runs `pre`, and is registered before the source overlay's transform, so
 * it sees the author's TypeScript with its type annotations and decorators
 * intact. HMR re-runs the transform for an edited module, which replaces its
 * entry; a deleted file drops its entry.
 *
 * @param enabled Read per call; off while DevTools is.
