docs: 标准化命令文档格式，移除表情符号并添加命令模板规范

更新所有命令文档以提高可读性和一致性：
- 移除所有表情符号（⚠️, ✅, ❌, ▸等），使用纯文本替代
- 统一标题格式，改进章节结构
- 简化状态指示器和格式标记
- 添加三个新的命令模板规范文档

新增文档：
- COMMAND_FLOW_STANDARD.md - 标准命令流程规范
- COMMAND_TEMPLATE_EXECUTOR.md - 执行器命令模板
- COMMAND_TEMPLATE_ORCHESTRATOR.md - 编排器命令模板

影响范围：
- CLI命令（cli-init, codex-execute, discuss-plan, execute）
- 内存管理命令（skill-memory, tech-research, workflow-skill-memory）
- 任务管理命令（breakdown, create, execute, replan）
- 工作流命令（所有workflow相关命令）
