fix: forward disable_thinking through the MCP generate_docs path

codewiki/mcp/server.py built its BackendConfig via from_cli() without passing
disable_thinking, so the new default always applied to MCP-triggered
generation and a persisted --enable-thinking was silently ignored. Forward the
persisted setting so the escape hatch works for MCP too.
