fix: Remove misleading task resumption message

This commit removes the misleading [TASK RESUMPTION] message that appears when a task is interrupted. The message was confusing the model and triggering unnecessary re-reads by suggesting things had changed when they hadn't.

<environment_details> will always be provided fresh with any necessary information, so the model should assume tasks are up to date.

Fixes: #5850
