CrazyBoyM 926df2cfaf feat: Ultra-redesign completion system with @mention integration
- Complete architectural overhaul of useUnifiedCompletion hook
- Unified state management: 8 separate states → single CompletionState interface
- Simplified core logic: getWordAtCursor 194 lines → 42 lines (78% reduction)
- Fixed infinite React update loops with ref-based input tracking
- Smart triggering mechanism replacing aggressive auto-completion
- Integrated @agent and @file mention system with system reminders
- Added comprehensive agent loading and mention processing
- Enhanced Tab/Arrow/Enter key handling with clean event management
- Maintained 100% functional compatibility across all completion types

Key improvements:
• File path completion (relative, absolute, ~expansion, @references)
• Slash command completion (/help, /model, etc.)
• Agent completion (@agent-xxx with intelligent descriptions)
• System command completion (PATH scanning with fallback)
• Terminal-style Tab cycling, Enter confirmation, Escape cancellation
• Preview mode with boundary calculation
• History navigation compatibility
• Empty directory handling with user feedback

Architecture: Event-driven @mention detection → system reminder injection → LLM tool usage
Performance: Eliminated 7-layer nested conditionals, reduced state synchronization issues
Reliability: Fixed maximum update depth exceeded warnings, stable state management

# Clean Architecture Solution
## 原则Keep It Simple
### ✅ 正确的设计
```typescript
// messages.tsx - 保持简洁
if (input.includes('@')) {
// 只处理文件引用
processedInput = await resolveFileReferences(processedInput)
}
```
### ❌ 错误的设计
- 在消息层检测 @agent
- 注入 system-reminder
- 修改用户输入
- 复杂的异步处理
## Agent 功能的正确实现
Agent 功能已经通过 Task 工具正确实现:
```typescript
// 用户可以直接使用
Task tool with subagent_type="dao-qi-harmony-designer"
```
不需要 @agent 语法糖,因为:
1. 增加了不必要的复杂性
2. 破坏了消息流的纯净性
3. 原始 Kode 没有这个功能
## 架构原则
1. **消息层**:只负责文件内容嵌入
2. **工具层**:处理 agent 配置
3. **模型层**:自然选择合适的工具
## 结论
移除所有 @agent 相关的复杂逻辑,保持原始的简洁设计。
