Concurrent-client isolation probe

The three tools have mostly distinct actions: probe_isolation runs a probe, get_verdict retrieves the latest verdict, and verify_receipt verifies a signed receipt. get_verdict and verify_receipt could be confused by an agent because both involve signed verdict artifacts, but the retrieve-versus-verify distinction is clear enough.

All tool names follow a consistent snake_case verb_noun pattern: get_verdict, probe_isolation, verify_receipt. The naming is predictable and readable across the set.

Three tools is appropriate for a narrow server focused on running isolation probes and handling signed verdicts. Each tool has a necessary role: execute the probe, retrieve the result, and verify the receipt.

The surface covers the core lifecycle of running a probe, retrieving a verdict, and verifying a receipt. Minor gaps exist, such as no tool to list endpoints, verdicts, or probe history, but the main workflow is not blocked.
