 * Create the Long Tail Human Queue MCP server.

 * - escalate_to_human -- create a new escalation (fire-and-forget)
 * - check_resolution -- check escalation status
 * - get_available_work -- list available escalations by role
 * - claim_and_resolve -- claim + resolve in one step
 * - resolve_escalation -- resolve an already-claimed escalation
 * - escalate_and_wait -- create escalation and return signal for durable wait
 *
 * The server is created with tools registered but no transport
 * auto-connected. Callers connect a transport programmatically
 * or via the Streamable HTTP endpoint.
