Advertise NDJSON operation outputs as arrays#1389

NDJSON endpoints (application/stream+json, x-ndjson, jsonl) declare the schema of one line, but the invoke path collects the stream and returns an array of parsed lines. Extraction stored the per-line schema unwrapped, so describe previews promised a single object that invocations never returned, pushing agents into runtime shape-probing (seen with Vercel getRuntimeLogs). Wrap the stored output schema in an array (with the truncation and raw-text caveats in its description) on both serve paths, share one NDJSON media-type set between extraction and invocation, and stale-mark affected connections via data migrations (sqlite ledger + cloud drizzle 0010) so existing catalogs rebuild with the corrected schemas.

NDJSON endpoints (
application/stream+json,x-ndjson,jsonl) declare the schema of one line, but invocations return an array of parsed lines. The advertised output schema now wraps the line schema in an array, so describe previews match what actually comes back. Existing integrations with NDJSON operations get stale-marked once (sqlite ledger + drizzle 0010) so their catalogs rebuild with the corrected schemas.New cross-target e2e scenario (
openapi-ndjson-output.test.ts) pins the contract end to end: register an NDJSON spec, compare the advertised type fromtools.schema/describe.toolagainst a live invocation. Green on cloud and selfhost.
