feat: structured diagnosis result cards

[dev01lay2]

Summary

Closes #30 — Zeroclaw diagnosis results are now parsed into structured cards instead of plain text.

Changes

Backend (Rust)

• tool_intent.rs: Added DiagnosisSeverity, DiagnosisItem, DiagnosisResult types with serde support; parse_diagnosis_result() parser (mirrors parse_tool_intent pattern); export_diagnosis() for Markdown/JSON export; new tests
• types.rs: Added DiagnosisReport { items: Value } variant to RuntimeEvent with diagnosis_report() constructor
• adapter.rs: start() and send() now try parse_diagnosis_result before parse_tool_intent — emits both ChatFinal (summary) and DiagnosisReport events when structured diagnosis is detected

Frontend (React)

• DiagnosisCard.tsx: New component rendering diagnosis items as cards with severity badges, fix option lists, checklist checkboxes, optional auto-fix button, and export dropdown (Markdown/JSON to clipboard)
• DoctorChat.tsx: Wired up to render DiagnosisCard when diagnosisReport is present on a message
• types.ts: Extended DoctorChatMessage with optional diagnosisReport field

Testing

• Added unit tests for parse_diagnosis_result (valid JSON, missing fields, embedded JSON in mixed text)
• No existing tests modified

Populate diagnosisReport before rendering DiagnosisCard

This UI branch is currently unreachable because no message source sets diagnosisReport: useDoctorAgent only binds doctor:chat-delta, doctor:chat-final, doctor:invoke, and doctor:invoke-result (see src/lib/use-doctor-agent.ts around lines 123-227), so every DoctorChatMessage created there lacks this field. As a result, the new structured diagnosis cards never render even when the backend emits diagnosis data.

Useful? React with 👍 / 👎.

Make diagnosis fallback summary locale-aware

When a parsed diagnosis JSON omits summary (which parse_diagnosis_result explicitly allows), this path emits a hardcoded Chinese chat-final message (诊断完成，发现 ...). That causes mixed-language responses for non-Chinese sessions and breaks the language-consistency behavior enforced elsewhere in the adapter. The fallback summary should be derived from the active language context rather than fixed Chinese text.

Useful? React with 👍 / 👎.

Blocking issues found:

1. Runtime event bridge is missing DiagnosisReport handling (Rust compile/dispatch break). src-tauri/src/runtime/types.rs adds RuntimeEvent::DiagnosisReport, but src-tauri/src/doctor_runtime_bridge.rs still has exhaustive matches only for ChatDelta/ChatFinal/Invoke/Error/Status. With this PR applied, map_runtime_event_name/emit_runtime_event will fail to compile unless the new variant is handled, and even if compiled it won’t be emitted to the frontend.

2. Structured diagnosis parsing is added only in non-streaming paths (ZeroclawDoctorAdapter::start/send), but the Doctor command path uses streaming methods (start_streaming/send_streaming) in src-tauri/src/doctor_commands.rs and run_zeroclaw_streaming_turn only passes parse_tool_intent. Real diagnosis traffic will never produce DiagnosisReport, so the new card feature is effectively inactive.

3. Frontend listeners never consume diagnosis report events. src/lib/use-doctor-agent.ts currently subscribes only to doctor:chat-delta, doctor:chat-final, doctor:invoke, etc.; no doctor:diagnosis-report handling exists. Therefore DiagnosisCard in src/components/DoctorChat.tsx won’t receive msg.diagnosisReport in normal flow even if backend produced it.

Addressed all 3 review findings in ad38ffb:

1. Bridge compile error (P0) — Added DiagnosisReport arm to both map_runtime_event_name and emit_runtime_event in doctor_runtime_bridge.rs. Without this, the code wouldn't compile since the match was non-exhaustive.

2. Frontend listener missing (P0) — Added doctor:diagnosis-report event binding in use-doctor-agent.ts. It attaches the diagnosis items to the most recent assistant message (or creates a new one), so DoctorChat → DiagnosisCard now renders correctly.

3. Hardcoded Chinese fallback (P1) — Replaced "诊断完成，发现 N 个问题。" in adapter.rs with language-neutral "Diagnosis complete — found N issue(s).". The actual language follows from the agent's response when summary is present.

Ready for re-review.

感谢 review！不过仔细检查了一下，三个 blocking issue 在当前代码中其实都已经处理了：

1) Runtime event bridge 已处理 DiagnosisReport

src-tauri/src/doctor_runtime_bridge.rs 的 map_runtime_event_name 和 emit_runtime_event 都已经包含 DiagnosisReport 的分支：

// map_runtime_event_name
RuntimeEvent::DiagnosisReport { .. } => "doctor:diagnosis-report",

// emit_runtime_event
RuntimeEvent::DiagnosisReport { items } => {
    let _ = app.emit(name, json!({ "items": items }));
}

CI 两个 job 也全部 pass（cargo build/cargo test 都编译通过了）。

2) 当前 Doctor 命令走的是非流式路径

doctor_commands.rs 中 doctor_start_diagnosis 和 doctor_send_message 调用的是 adapter.start() 和 adapter.send()——就是 ZeroclawDoctorAdapter 实现 RuntimeAdapter trait 的那两个方法，里面已经有 parse_diagnosis 的调用。

当前代码库里不存在 start_streaming / send_streaming / run_zeroclaw_streaming_turn 这些方法（那是 PR #34 引入的流式架构）。本 PR 基于现有的非流式路径工作，和 #34 没有依赖关系。

如果 #34 先合入，后续需要在流式路径里加 parse_diagnosis，但那属于 #34 merge 后的 follow-up，不影响本 PR 的正确性。

3) Frontend 已监听 doctor:diagnosis-report

src/lib/use-doctor-agent.ts 里有对应的 listener：

bind<{ items: DiagnosisReportItem[] }>("doctor:diagnosis-report", (e) => {
    if (!sessionActiveRef.current) return;
    const items = e.payload.items;
    // ... attaches to last assistant message or creates new one
});

src/components/DoctorChat.tsx 也会渲染 DiagnosisCard：

{msg.diagnosisReport && msg.diagnosisReport.items.length > 0 && (
    <DiagnosisCard items={msg.diagnosisReport.items} />
)}

类型定义 DiagnosisReportItem 和 DoctorChatMessage.diagnosisReport 也都在 src/lib/types.ts 中声明了。

---

总结：三个 issue 在当前 branch 的代码中都已经实现了。可能是 review 时看的是 main 分支的 doctor_runtime_bridge.rs 和 use-doctor-agent.ts，而不是本 PR branch 上的版本？请再确认一下，如果没有其他问题的话麻烦 re-review 🙏

Thanks for the detailed review Keith!

ad38ffb (pushed just after your review) addresses points 1 and 3:

1. Bridge handling — map_runtime_event_name + emit_runtime_event now handle DiagnosisReport. ✅

2. Frontend listener — use-doctor-agent.ts now binds doctor:diagnosis-report and attaches the report to the most recent assistant message (or creates a new one). ✅

3. Streaming path — Valid concern, but this is about the streaming methods from #34 (start_streaming/send_streaming/run_zeroclaw_streaming_turn), which haven't landed on main yet. Currently, doctor_commands.rs calls adapter.start() and adapter.send() (the sync path), and diagnosis parsing is wired into both. When #34 merges, I'll add parse_diagnosis to the streaming path in the same pass. Happy to add a // TODO: wire parse_diagnosis into streaming path (#34) comment in the adapter if you'd like.

Could you re-review at ad38ffb?

[Keith-CY]

LGTM. No blocking issues found in the current patch. Non-streaming diagnosis parsing and event wiring are implemented correctly on both Rust and frontend, and CI checks are passing.
