Why: models need a capped way to call several tools from one script, and a slow MCP server must not block the first prompt.
Evidence: GOWORK=off go test ./runtime/codeorch/ ./runtime/tools/ ./runtime/mcp/ ./runtime/policy/ ./adapters/native/
Impact: run_tool_script stays unregistered until the caller turns it on. Deferred tools stay out of the model list. An unready MCP server connects in the background.
