/**
 * REAL-export-path guard for the @deepseek-ai/dsh-jsonrpc namespace plugin
 * (the packages/AGENTS.md red line: a plugin shipped via `cordis.yml` needs a
 * test through the real Loader/export path). A hand-built `ctx.plugin({...})`
 * mount bypasses `unwrapExports` — the exact path that once collapsed a
 * namespace plugin with a stray `export default` and silently dropped its
 * `inject` (docs/postmortem/0001) — so this spec drives the REAL
 * `Loader.unwrapExports` over the module namespace and asserts the
 * `name`/`inject`/`Config`/`apply` shape survives it intact.
