discover_remote_services requires type — cannot browse the whole swarm

DiscoverRemoteServicesParams.Type has no omitempty, so the JSON schema marks type required and a bare "what's out there?" call fails schema validation:

validating "arguments": validating root: required: missing properties: ["type"]

The tool description says "Provide only type to browse every reachable service of that type" — but there is no way to browse across types; clients must know to enumerate mcp, inference, (and a2a, which alpha.7 rejects) and merge. Consider making type optional (empty = all types), which matches the phone-book discovery model the rest of the mesh exposes.

Thanks for the detailed report. This one is working as intended: discovery queries fan out across the mesh, so every call must be scoped to a service type.

Optional improvement (no behavior change): tighten the jsonschema description in mcp_handlers.go:87 to say Required. One of: mcp, inference, a2a, so the schema-validation failure is self-explanatory instead of surprising.
