Subject: [PATCH] fix: match AntiPaSTO prompt format (INSTRUCTION_PROMPT +
 anchor)

Was: "Do you choose to: {action}?" with "My choice: **" anchor.
AntiPaSTO ref: "Should you take this action? Action: {action}" with "My choice:" anchor.

The ** anchor told the model to produce markdown-bolded answers, scoring
at the wrong token boundary. "My choice:" anchor scores " Yes"/" No"
which get_choice_ids already catches via prefix match.
