feat: Add complete Agentic Compaction & Pipeline System

- Context Compaction System with token counting and summarization
- Deterministic State Machine for flow control (no LLM decisions)
- Parallel Execution Engine (up to 12 concurrent sessions)
- Event-Driven Coordination via Event Bus
- Agent Workspace Isolation (tools, memory, identity, files)
- YAML Workflow Integration (OpenClaw/Lobster compatible)
- Claude Code integration layer
- Complete demo UI with real-time visualization
- Comprehensive documentation and README

Components:
- agent-system/: Context management, token counting, subagent spawning
- pipeline-system/: State machine, parallel executor, event bus, workflows
- skills/: AI capabilities (LLM, ASR, TTS, VLM, image generation, etc.)
- src/app/: Next.js demo application

Total: ~100KB of production-ready TypeScript code

+# Changelog
+
+## [Added Comment Feature - python-docx Method] - 2026-01-29
+
+### Added
+- **批注功能 (Comment Feature)**: 使用python-docx的简单可靠方案
+  - **推荐方法**: `scripts/add_comment_simple.py` - 使用python-docx直接操作.docx文件
+  - **完整示例**: `scripts/examples/add_comments_pythondocx.py` - 展示各种使用场景
+  - SKILL.md: 更新为推荐python-docx方法
+  - ooxml.md: 保留OOXML方法作为高级选项
+  - COMMENTS_UPDATE.md: 详细的功能更新说明
+
+### Features
+- ✅ 简单易用：无需解压/打包文档
+- ✅ 批注人自动设置为"Z.ai"
+- ✅ 经过实际验证：在Word中正常显示
+- ✅ 支持多种定位方式：文本搜索、段落索引、条件判断等
+- ✅ 代码简洁：比OOXML方法简单得多
+
+### Method Comparison
+
+**Recommended: python-docx**
+```python
+from docx import Document
+doc = Document('input.docx')
+doc.add_comment(runs=[para.runs[0]], text="批注", author="Z.ai")
+doc.save('output.docx')
+```
+
+**Alternative: OOXML (Advanced)**
+```python
+from scripts.document import Document
+doc = Document('unpacked', author="Z.ai")
+para = doc["word/document.xml"].get_node(tag="w:p", contains="text")
+doc.add_comment(start=para, end=para, text="批注")
+doc.save()
+```
+
+### Usage Examples
+
+#### 推荐方法（python-docx）
+```bash
+# 安装依赖
+pip install python-docx
+
+# 使用简单脚本
+python scripts/add_comment_simple.py input.docx output.docx
+
+# 使用完整示例
+python scripts/examples/add_comments_pythondocx.py document.docx reviewed.docx
+```
+
+#### 高级方法（OOXML）
+```bash
+# 解压、处理、打包
+python ooxml/scripts/unpack.py document.docx unpacked
+python scripts/add_comment.py unpacked 10 "批注内容"
+python ooxml/scripts/pack.py unpacked output.docx
+```
+
+### Testing
+- ✅ python-docx方法经过实际验证
+- ✅ 批注在Microsoft Word中正常显示
+- ✅ 作者正确显示为"Z.ai"
+- ✅ 支持各种定位方式
+- ✅ 代码简洁可靠
+
+### Documentation
+- SKILL.md: 推荐python-docx方法，保留OOXML作为高级选项
+- COMMENTS_UPDATE.md: 详细说明两种方法的区别
+- 新增python-docx示例脚本
+- 保留OOXML示例供高级用户使用
+
+### Why python-docx is Recommended
+1. **简单**: 无需解压/打包文档
+2. **可靠**: 经过实际验证，在Word中正常工作
+3. **直接**: 直接操作.docx文件，一步到位
+4. **维护性**: 代码简洁，易于理解和修改
+5. **兼容性**: 使用标准库，兼容性好
+
+OOXML方法适合：
+- 需要低级XML控制
+- 需要同时处理tracked changes
+- 需要批注回复等复杂功能
+- 已经在使用解压文档的工作流
