/**
 * Regression test for #8374 — GET /api/plugins returns "Invalid status value"
 * when no `?status=` filter is passed.
 *
 * Root cause: `URLSearchParams.get("status")` returns `null` (not `undefined`)
 * when the query param is absent. `z.enum([...]).optional()` widens the schema
 * to accept `undefined`, but NOT `null` — so `safeParse(null)` fails and the
 * route returns HTTP 400, even though the caller passed no filter at all.
 *
 * Fix: coerce `null` -> `undefined` before handing it to Zod, matching the
 * repo's own established idiom (see registered-keys/route.ts,
 * suggested-models/route.ts, quota/preview/route.ts).
