Add TypedDicts for DEFAULT_CONFIG, CLI state dicts (_ModelPickerState, _ApprovalState, _ClarifyState), and OPTIONAL_ENV_VARS so ty can resolve nested dict subscripts. Guard Optional returns before subscripting (toolsets, cron/scheduler, delegate_tool), coerce str|None to str before slicing (gateway/run, run_agent), split ternary for isinstance narrowing (wecom), and suppress discord interaction.data access with ty: ignore.
