feat: Add startup scripts and service configuration files

- Added start_compatible.sh for Python 3.6 compatibility
- Added start_optimized.sh with memory limits and port checking (recommended)
- Added start_ultralight.sh for resource-constrained environments
- Added servo-sizer.service systemd service file
- Added lightweight_server.py optimized HTTP server
- Added monitor.sh process monitoring script
- Added chart.js local Chart.js library
- Added .server.pid for process management

+# 伺服驱动选型工具改进计划
+
+## 当前问题分析
+1. **HTML/JS 不匹配**：HTML 使用 select 元素，但 JS 代码期望按钮点击
+2. **DOM 元素缺失**：缺少 results、transmission-type 等关键元素
+3. **功能不完整**：动态参数表单未实现，图表功能缺失
+4. **用户体验问题**：缺少输入验证反馈和错误处理
+
+## 改进目标
+- ✅ 修复 HTML/JS 结构不匹配问题
+- ✅ 实现完整的动态参数表单系统
+- ✅ 添加 Chart.js 图表可视化
+- ✅ 增强输入验证和错误处理
+- ✅ 优化用户界面和交互体验
+- ✅ 完善文档和使用说明
+
+## 技术实现方案
+1. **统一使用 select 元素**进行传动类型选择（更符合实际需求）
+2. **动态生成参数表单**基于选择的传动类型
+3. **重构计算逻辑**为模块化函数
+4. **添加完整的图表支持**使用 Chart.js
+5. **增强错误处理**和用户反馈机制
