Summary

The MCP server now sends Pulsar admin and Kafka Connect requests to the cluster endpoint directly, not through the proxy.

Changes

• getBasePath(proxyLocation, org, clusterID) → getWebServiceURL(dnsName): https://<cluster service endpoint>.
• Kafka Connect URL: <proxy>/admin/kafkaconnect/ → https://<cluster service endpoint>/admin/kafkaconnect/. This matches what snctl uses for direct connections.
• The cluster's service endpoint was already required (the context setup fails without one), and the Pulsar binary protocol and Schema Registry URLs already used it.
• --proxy-location and proxy-location config stay for compatibility, but the Pulsar context no longer uses them.

Testing

• go build ./..., go vet ./pkg/mcp/, go test ./pkg/mcp/ pass. New TestClusterEndpointURLs.
• The same direct-endpoint behavior was verified with snctl and a service account key against the test environment (streamnative/cloud-cli#270).

Release note

snctl mcp embeds this module (cloud-cli pins v0.1.10), so snctl needs a dependency bump after this is released.
