/**
 * Capability Invoke — late-binding MCP tool invocation.
 *
 * A minimal durable workflow that calls a single MCP server tool.
 * Used by agent automation subscriptions with reaction_type 'capability'.
 *
 * The durable wrapper provides:
 * - Request idempotency via deterministic workflow ID
 * - Crash safety via HotMesh activity retry
 * - Audit trail via workflow execution records
 * - _scope threading via the interceptor
