[BUG] Plan mode doesn't exit after user approves plan and instructs execution

Preflight Checklist

What's Wrong?

When ExitPlanMode is rejected by the user with an instruction to proceed (e.g., "yes create this and test in localhost first"),
plan mode remains active in system reminders even though the user clearly approved and wants execution. The system keeps sending
"Plan mode still active" reminders throughout the entire implementation, commit, and deploy process. The mode should automatically
exit when the user responds to ExitPlanMode with an approval + execution instruction.

What Should Happen?

should have got out side of plan mode
