/**
* Real-load-path guard for @deepseek-ai/dsh-tool-fs-search. `tool-fs-search` is
* a NAMESPACE plugin with `inject` — so a stray `export default apply` would
* make the cordis Loader's `unwrapExports` (`exports.default ?? exports`)
* collapse the module to the bare `apply` function, DROPPING `inject`. The
* plugin would then read `ctx.bash` without having injected it and throw
* `cannot get property … without inject` the moment it loads (postmortem 0001).
*
* A hand-built `ctx.plugin({ apply, inject })` mount CANNOT catch that — it
* bypasses `unwrapExports`. So this test unwraps the module through the REAL
* `Loader.prototype.unwrapExports` and mounts the result over a bash executor,
* exercising the exact path the Loader uses. Prove the guard bites: add
* `export default apply` to `src/index.ts`, watch this go red, revert.
