netx-mcp 0.3.1: fix alarm paging, tool-level arg errors, leaner outputs.

- queryNmsAlarms no longer silently clamps page to 2; add is_cleared.
- Bad integer args return invalid_argument tool errors instead of JSON-RPC crashes.
- Nested {"ok": true, "data": {"ok": false}} results are flagged isError.
- stdio: answer ping, never respond to notifications, version from metadata.
- getNmsNe resolves exact host_name/IP; severity lowercased.
- Outputs use nms_ne_id/source=nms; drop ME{uuid} names, echoed field lists, idle hop_* fields.
- Fabric paths: parallel links count as one hop (edges[].parallel_links).
