One review instruction for the prompts that run the review #487

#486

What to build

Four Session prompts repeat the code review's wording: the implement session's, fresh and Continuation, the Spec review's, and that of the Repair that reviews Foreign commits. Give them one review instruction, worded once in the prompt module, for each of the four to use. A later change to how findings are handled then lands in one place. Nothing an agent is told changes, so the prompts page stays exactly as it is.

Acceptance criteria

• The implement session (fresh and Continuation), the Spec review and the Repair that reviews Foreign commits take their review wording from one shared instruction: addressing the findings the agent agrees with, and the Unaddressed findings section.
• Each prompt keeps its own variations. The Spec review still uses the thirdshift-tdd skill and commits. The Repair still marks its entries as coming from the Foreign commits, adds them to the existing section and keeps the rest of the body.
• Regenerating the prompts page changes nothing in it.
• No other prompt changes.
