Subject: [PATCH] fix: reset UI state when canceling during streaming to
 prevent frozen cancel button

This fixes issue #9529 where the cancel button would get stuck/frozen when attempting to cancel a task during an API request. The UI state variables (sendingDisabled, clineAsk, enableButtons) are now properly reset when canceling during streaming, allowing the UI to return to the correct state and show the "new task" and "terminate" buttons.

Fixes #9529
