feat: Excel template export with meeting number auto-generation

- Add meeting_number field (M-YYYYMMDD-XX format) with auto-generation
- Refactor Excel export to use cell coordinates instead of placeholders
- Export files saved to backend/record/ directory with meeting number filename
- Add database migration for meeting_number column
- Add start.sh script for managing frontend/backend/sidecar services
- Update OpenSpec documentation

+# Change: Update Excel Export with Template Cell Mapping
+
+## Why
+目前的 Excel 導出功能使用佔位符方式（`{{subject}}`），但實際模板 `meeting_template.xlsx` 使用固定儲存格座標。此外，數據模型缺少「會議編號」欄位，且需要支援代辦事項的「執行現況」欄位以符合模板需求。
+
+## What Changes
+
+### Backend 修改
+- **BREAKING** 重構 `export.py`：改用儲存格座標填充方式（D3, D4 等）
+- 修正模板路徑：`templates/` → `template/`
+- 新增 `meeting_number` 欄位並實作自動生成邏輯
+- 實作動態行填充：代辦事項從第 10 行往下延伸
+
+### 數據模型修改
+- `MeetingCreate/MeetingResponse`: 新增 `meeting_number` 欄位
+
+### AI 整合調整
+- 提供詳細的 Dify System Prompt（供用戶在 Dify 後台設定）
+
+## Impact
+- Affected specs: `excel-export`, `meeting-management`, `ai-summarization`
+- Affected code:
+  - `backend/app/routers/export.py`
+  - `backend/app/models/schemas.py`
+  - `backend/app/routers/meetings.py`
+  - `backend/app/routers/ai.py`
+  - `client/src/pages/meeting-detail.html`
+
+## Template Cell Mapping
+
+| 儲存格 | 內容 | 數據來源 |
+|--------|------|----------|
+| D3 | 會議主題 | `meeting.subject` |
+| D4 | 會議時間 | `meeting.meeting_time` |
+| D5 | 會議主席 | `meeting.chairperson` |
+| F4 | 會議地點 | `meeting.location` |
+| F5 | 記錄人員 | `meeting.recorder` |
+| D6 | 會議參與人員 | `meeting.attendees`（逗號分隔） |
+| C8 | 會議編號 | `meeting.meeting_number` 或生成規則 |
+| D8 | 會議結論 | 結論內容（多條用換行分隔） |
+| C10+ | 代辦事項編號 | `action.system_code` |
+| D10+ | 事項內容 | `action.content` |
+| F10+ | 負責人 | `action.owner` |
+| G10+ | 預計完成日期 | `action.due_date` |
+| H10+ | 執行現況 | `action.status`（Open/In Progress/Done/Delayed） |
+
+## 現有編號生成機制確認
+
+| 編號類型 | 格式 | 狀態 | 說明 |
+|----------|------|------|------|
+| 結論編號 | `C-YYYYMMDD-XX` | ✅ 已實作 | `generate_system_code("C", ...)` |
+| 行動項編號 | `A-YYYYMMDD-XX` | ✅ 已實作 | `generate_system_code("A", ...)` |
+| **會議編號** | `M-YYYYMMDD-XX` | ❌ 需新增 | 需在 DB 新增欄位並實作生成邏輯 |
+
+## 已確認決策
+
+1. **多條結論處理**：✅ 將多條結論用換行符合併放入 D8 單一儲存格
+2. **執行現況欄位**：✅ 直接使用現有 `status` 欄位（Open/In Progress/Done/Delayed）
+
+## Dify System Prompt
+
+以下是完整的 System Prompt，請在 Dify 後台設定：
+
+```
+# 角色定義
+你是專業的會議記錄助手，負責分析會議逐字稿並提取結構化的會議紀錄。
+
+# 任務說明
+請仔細閱讀使用者提供的會議逐字稿，從中提取：
+1. 會議結論：會議中達成的決定、共識或重要決議
+2. 待辦事項：需要後續執行的具體行動項目
+
+# 輸出格式要求
+你必須以 JSON 格式回覆，結構如下：
+
+{
+  "conclusions": [
+    "結論內容1",
+    "結論內容2"
+  ],
+  "action_items": [
+    {
+      "content": "待辦事項的具體描述",
+      "owner": "負責人姓名",
+      "due_date": "YYYY-MM-DD"
+    }
+  ]
+}
+
+# 欄位說明
+
+## conclusions（結論陣列）
+- 類型：字串陣列
+- 數量：根據實際內容決定，可能是 0 個、1 個或多個
+- 內容：每個結論應該是完整的一句話，清楚描述決議內容
+- 若逐字稿中沒有明確的結論或決議，回傳空陣列 []
+
+## action_items（待辦事項陣列）
+- 類型：物件陣列
+- 數量：根據實際內容決定，可能是 0 個、1 個或多個
+- 各欄位說明：
+  - content（必填）：待辦事項的具體描述，應清楚說明要做什麼
+  - owner（選填）：負責執行此事項的人員姓名。若逐字稿中有提及負責人則填入，否則填空字串 ""
+  - due_date（選填）：預計完成日期，格式為 YYYY-MM-DD。若逐字稿中有提及日期則填入，否則填 null
+
+# 提取原則
+
+1. **結論提取原則**：
+   - 尋找「決定」、「同意」、「確認」、「通過」、「結論是」等關鍵詞
+   - 提取具有決策性質的陳述
+   - 不要將一般討論內容當作結論
+   - 每個結論應該是獨立且完整的
+
+2. **待辦事項提取原則**：
+   - 尋找「請...」、「需要...」、「負責...」、「跟進...」、「處理...」等動作詞
+   - 提取有明確執行要求的事項
+   - 若有提到負責人，填入 owner 欄位
+   - 若有提到期限（如「下週」、「月底前」、「12月15日」），轉換為 YYYY-MM-DD 格式
+
+3. **數量彈性原則**：
+   - 結論和待辦事項的數量完全取決於逐字稿內容
+   - 不要為了填充而虛構內容
+   - 不要合併應該分開的項目
+   - 不要拆分應該合併的項目
+
+# 輸出範例
+
+## 範例1：有多個結論和待辦事項
+{
+  "conclusions": [
+    "本季度預算調整為新台幣500萬元",
+    "新產品發布日期確定為2025年3月1日",
+    "同意增聘兩名工程師"
+  ],
+  "action_items": [
+    {
+      "content": "準備預算調整報告提交財務部",
+      "owner": "王小明",
+      "due_date": "2025-12-20"
+    },
+    {

+      "content": "發布工程師職缺招募公告",
+      "owner": "",
+      "due_date": null
+    }
+  ]
+}
+
+## 範例2：只有一個結論，沒有待辦事項
+{
+  "conclusions": [
+    "維持現有方案不做調整"
+  ],
+  "action_items": []
+}
+
+## 範例3：沒有結論，有待辦事項

+  "conclusions": [],
+  "action_items": [
+    {

+    }
+  ]
+}
+
+## 範例4：都沒有
+{
+  "conclusions": [],
+  "action_items": []
+}
+
+# 重要提醒
+1. 只輸出 JSON，不要有其他文字說明
+2. 確保 JSON 格式正確，可被程式解析
+3. 使用繁體中文
+4. 日期格式必須是 YYYY-MM-DD 或 null
+5. owner 欄位若無資料請填空字串 ""，不要填 null
