/**
 * `qodo-skills` path helpers — browser stub.
 *
 * The Node version reaches `node:fs` / `node:path` to canonicalise the
 * skill directory and re-canonicalise the requested file at the moment
 * of resolution (closes TOCTTOU symlink-swap windows). Neither API
 * exists in the browser, and skills discovery is itself Node-only (see
 * `manager.browser.ts` for the rationale).
 *
 * The stubs throw immediately so a browser consumer who somehow reaches
 * this code path — by configuring `ClientOptions.skills` in a browser
 * build — gets a typed `SkillPathError` instead of a cryptic
 * `Cannot read properties of undefined` deep in their bundler output.
 *
 * The matching swap is wired via `package.json#browser`.
