[Bug] Auto mode unavailable error persists despite mode change in session

Bug Description
I had auto as default mode in settings.json at ~/.claude and whenever I ask any question, like a simple hi it returns ● Auto mode is unavailable for your plan --- changed mode to ask in the same session and it returned same response. only worked when changing the default mode in settings file to plan. didn't try if changing to accept edit mode will change the mode. the issue most likely either changing mode function or mode set in settings can't be changed. this is degradation. just updated claude code to 2.1.90 (Claude Code).
