Add scripts/smoke_mcp.py, same shape as smoke_rest_api.py (random port,
subprocess-launch against QONTO_FIXTURE_DIR, wait on /v1/health, assert,
clean teardown), but goes further: generates a fresh
QONTO_ASSISTANT_MCP_TOKEN per run and connects through it with the mcp
SDK's streamablehttp_client, so the smoke exercises T03's bearer-token gate
instead of bypassing it. Lists tools, calls all four, and confirms an
out-of-catalog tool name comes back as a normal isError result through the
real wire protocol rather than a crash.
Extend docs/operator-runbook.md with a "One-command MCP smoke" section next
to the REST one; cross-link from docs/mcp-integration.md's manual smoke
walkthrough so the two don't drift.
