fix(todo-continuation-enforcer): persist errorBypass mode until user sends message

Previously, errorBypass mode was cleared on session.idle, causing continuation
to fire again on next idle event. This led to unwanted task resumption after
user abort.

Changes:
- Don't clear errorBypass on session.idle - stay in errorBypass mode
- Clear errorBypass to idle only when user sends a new message

This ensures that once user aborts, the enforcer respects that decision until
the user explicitly sends a message to resume.
