91cab452d1 fix(dc/tool-c): Fix special character handling and improve UX
Major fixes:
- Fix pivot transformation with special characters in column names
- Fix compute column validation for Chinese punctuation
- Fix recode dialog to fetch unique values from full dataset via new API
- Add column mapping mechanism to handle special characters

Database migration:
- Add column_mapping field to dc_tool_c_sessions table
- Migration file: 20251208_add_column_mapping

UX improvements:
- Darken table grid lines for better visibility
- Reduce column width by 40% with tooltip support
- Insert new columns next to source columns
- Preserve original row order after operations
- Add notice about 50-row preview limit

Modified files:
- Backend: SessionService, SessionController, QuickActionService, routes
- Python: pivot.py, compute.py, recode.py, binning.py, conditional.py
- Frontend: DataGrid, RecodeDialog, index.tsx, ag-grid-custom.css
- Database: schema.prisma, migration SQL

Status: Code complete, database migrated, ready for testing

f729699510 feat(dc): Complete Tool C quick action buttons Phase 1-2 - 7 functions
Summary:
- Implement 7 quick action functions (filter, recode, binning, conditional, dropna, compute, pivot)
- Refactor to pre-written Python functions architecture (stable and secure)
- Add 7 Python operations modules with full type hints
- Add 7 frontend Dialog components with user-friendly UI
- Fix NaN serialization issues and auto type conversion
- Update all related documentation

Technical Details:
- Python: operations/ module (filter.py, recode.py, binning.py, conditional.py, dropna.py, compute.py, pivot.py)
- Backend: QuickActionService.ts with 7 execute methods
- Frontend: 7 Dialog components with complete validation
- Toolbar: Enable 7 quick action buttons

Status: Phase 1-2 completed, basic testing passed, ready for further testing

f01981bf78 feat(dc/tool-c): 完成AI代码生成服务(Day 3 MVP)
核心功能:
- 新增AICodeService(550行):AI代码生成核心服务
- 新增AIController(257行):4个API端点
- 新增dc_tool_c_ai_history表:存储对话历史
- 实现自我修正机制:最多3次智能重试
- 集成LLMFactory:复用通用能力层
- 10个Few-shot示例:覆盖Level 1-4场景

技术优化:
- 修复NaN序列化问题(Python端转None)
- 修复数据传递问题(从Session获取真实数据)
- 优化System Prompt(明确环境信息)
- 调整Few-shot示例(移除import语句)

测试结果:
- 通过率:9/11(81.8%) 达到MVP标准
- 成功场景:缺失值处理、编码、分箱、BMI、筛选、填补、统计、分类
- 待优化:数值清洗、智能去重(已记录技术债务TD-C-006)

API端点:
- POST /api/v1/dc/tool-c/ai/generate(生成代码)
- POST /api/v1/dc/tool-c/ai/execute(执行代码)
- POST /api/v1/dc/tool-c/ai/process(生成并执行,一步到位)
- GET /api/v1/dc/tool-c/ai/history/:sessionId(对话历史)

文档更新:
- 新增Day 3开发完成总结(770行)
- 新增复杂场景优化技术债务(TD-C-006)
- 更新工具C当前状态文档
- 更新技术债务清单

影响范围:
- backend/src/modules/dc/tool-c/*(新增2个文件,更新1个文件)
- backend/scripts/create-tool-c-ai-history-table.mjs(新增)
- backend/prisma/schema.prisma(新增DcToolCAiHistory模型)
- extraction_service/services/dc_executor.py(NaN序列化修复)
- docs/03-业务模块/DC-数据清洗整理/*(5份文档更新)

Breaking Changes: 无

总代码行数:+950行
