Pull request overview
This PR adds request-scoped authentication token forwarding across HTTP/SSE tool invocations and introduces an optional external “ONTAP KG” discover endpoint to handle ontap_discover ranking remotely with a local index fallback.
Changes:
- Add AsyncLocalStorage-based per-request access token context, extracted from HTTP headers and optionally injected via an internal tool argument.
- Update ONTAP/NetApp clients to prefer the request token over ADC when present.
- Add optional KG discover client + protocol/schema/docs and integrate KG querying into
ontap_discoverwith fallback.
