/**
 * MRSF string (de)serialization — pure, dependency-light helpers that parse and
 * serialize MRSF sidecar content to/from strings.
 *
 * This module intentionally has **no Node-only imports** (no `node:fs`,
 * `node:path`, `node:crypto`, …) so it can be consumed from browser/host
 * adapters via the slim `@mrsf/cli/browser` entry point. Filesystem-bound
 * helpers (read/discover/write a file) live in `parser.ts` / `writer.ts`.
