fix(coding-agent): detect non-English questions in todo reminder guard

The isAwaitingUserAnswer guard that suppresses the todo completion reminder while the agent waits on a user question only recognized English question words and pronouns. A '？'/'?'-terminated Chinese, Japanese, Korean, or Spanish prompt went undetected, so the <system-reminder> interrupted the pause and the model misread it as the user's answer.

isQuestionPromptLine now also treats a question-mark-terminated line containing any non-ASCII character as a pending user question.

Fixes #7803

 ## [Unreleased]
 
+### Fixed
+
+- Fixed the todo completion reminder still firing while the agent was waiting on a user question asked in a non-English language. The `isAwaitingUserAnswer` guard only recognized English question words and pronouns, so a `？`/`?`-terminated Chinese, Japanese, Korean, or Spanish prompt (e.g. `我应该继续吗？`) went undetected and the `<system-reminder>` interrupted the pause — which the model then misread as the user's answer and acted on. A trailing question mark plus any non-ASCII character in the line now counts as a pending question ([#7803](https://github.com/can1357/oh-my-pi/issues/7803)).
