Fixes request-scoped ClickHouse client config overrides getting lost when run_query executes in QUERY_EXECUTOR.
The server now captures FastMCP context state before the thread-pool handoff, deep-copies valid
clickhouse_client_config_overrides, and passes them explicitly into the worker path. This preserves per-requestsettings.rolefor shared long-lived MCP server usage without relying on contextvars inside executor threads.
