fix(summarize): 兼容 role:"tool" 形状的工具结果 - #353
Conversation
DSH 0.2.x 的 session/event 投递 tool/result 时，载荷与 isError 已从 content 内的 `type:"tool-result"` 块迁到 `role:"tool"` 消息本身。蒸馏只按块形状取值，新形状 落进 undefined 分支，工具输出与工具报错被静默丢弃。 保留旧块形状优先（legacy ?? message），新旧两种形状都能采集。

几个值得点名的地方:
- 认领前先扫了 1095 条真实事件,把「静默失效」钉成实锤——排查数据扎实,修复的动机与证据链完整;
- 范围严格卡在
tool/result单点,tool/call的边界主动拎出来讨论而不是顺手扩大; - 旧块形状优先、
role:"tool"消息回退,退化输入全部落回旧行为;既有toolResultEvent断言原封不动,覆盖只增不减; - sync 产物、双 README 徽章、stash 验证回归有效性——全套闸门一次过,流程干净利落。

1080-1100: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win为混合形状增加旧块优先级断言。
当
data.message同时包含role: "tool"和type: "tool-result"块时，必须选择旧块。否则，textOf(message.content)会忽略旧块中的嵌套文本，并可能使用错误的消息级isError。这会改变转录内容和成功/失败状态。当前测试把两种形状放在不同事件中。它无法检测该优先级回归。请在本测试中加入混合形状断言。

背景
蒸馏从会话事件里采集工具结果时，
tool/result事件的内容有两种形状，而 0.8.x 只认其中一种，新形状下落进undefined分支——工具输出与工具报错被静默丢弃，不进 transcript。isError装在data.message.content内的type: "tool-result"块上。role: "tool"消息本身，content里只有type: "text"块，isError挂在消息上。扫本机最近 14 个 v4 会话日志：
tool/result事件 1095 个，1095/1095 全是新形状，旧形状命中 0，其中 77 个isError: true。也就是现有取值对这 1095 个全部返回undefined，不是偶发。改动
只改
tool/result分支的取值方式，下游textOf/isError/trim一律不动：按内容形状判定而不是按 DSH 版本分支，跟
textOf已有的严格/宽松双兼容是同一个思路，新旧内核都成立。旧块优先、消息回退，旧形状行为完全不变。tool/call不在本次范围内：它读的是data.name/data.arguments，与 content 块形状是两条路径。测试
test/summarize.test.js新增一个role:"tool"事件构造 helper（既有toolResultEvent旧块形状 helper 与其断言保持不动），两个用例：isError: true三条都被采进 transcript，状态词分别正确；验证
node scripts/check-sync.js通过（51 个文件src/↔lib/一致）；lib/产物由npm run sync生成并一并提交。npm test：ℹ tests 1481 / ℹ pass 1480 / ℹ fail 0 / ℹ skipped 1。src/summarize.js+lib/summarize.js的改动 stash 掉重跑，两个新用例会红（✖×2），恢复后全绿。npm run badge:sync重算测试数，双 README 徽章与注释由 1479 更新为 1481（= 1479 + 本 PR 的 2 个用例），test-count-sync.test.js一致。关联
Closes #351
与 #211 的边界：#211 修的是
tool/result/tool/code-dispatch读不存在的data.output，以及agent/inbox/spliced的 switch 覆盖；本次是data.message.content内的块形状已变导致取值恒为undefined，两者不重叠。Summary by CodeRabbit
