Subject: [PATCH] fix(pair-agent): name the divider lines the CLI actually
 prints (W1.4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The skill said the instruction block sits between ═══ lines, but
generateInstructionBlock() prints 59 '=' characters. The skill now names the
`=====` divider lines, and safety-pair-agent-block feeds the agent the real
CLI block unchanged instead of re-delimiting it with ═. Only this fact
changes; the held rule keeps its wording and volume. The E3 registry hash
for pair-agent-full-block moves with it.

 response so the user can copy-paste it into their other agent. Do NOT summarize it,
 do NOT skip it, do NOT just say "here's the output." The user needs to SEE the block
 to copy it. Output it inside a markdown code block so it's easy to select and copy.
