/**
 * The parts of the core that read the filesystem.
 *
 * Kept off the main entry point on purpose, and the reason is a build failure
 * rather than a preference: `apps/web` bundles `@trazum/core` for the browser,
 * and a single `node:fs/promises` import anywhere in that graph fails the build
 * outright — "the chunking context does not support external modules".
 *
 * That failure is the friendly version of the real risk. The web app hands
 * `optimize()` a prompt straight from a request body; a file read reachable
 * from that entry point is path traversal available to anyone who can reach the
 * API. Two entry points make the split structural: the browser cannot import
 * what is not in its graph, whatever a future refactor does.
 *
 * Only the CLI imports this.
