Subject: [PATCH] Resolve backend pin to merge of EXT-8b and fast-slow lines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Why: origin/main 已并行推进 backend pin 至 4d48aba（fast-slow 线）；本任务 EXT-8b 线 830fea3 与其为 5e8ada7 后的兄弟分支——直接指 830fea3 会回退他人已合入内容（memory: dev pin 丢内容教训）。
Evidence: merge/ext8b-fastslow=8e50977（Backend 仓，build+runmgr/server/extension 三套件绿）；组合验证见任务卡。
Impact: gitlink 指两线合并；不回退任何已合入提交。
