New agent tasks defaulted to Bypass whenever the provider offered it, whatever the user had chosen. A task now starts with the settings shown in the composer: the provider's reported mode, or Ask for Cursor. An explicit choice is kept, including Bypass, and running tasks keep their own mode. Cached provider settings could hold a Bypass written automatically with no record of its source, so a cached bypass is dropped on load, read and save while the option stays offered.
