feat: Friend 消息 → 仅使用人设提示词

修改的文件 (5个)

核心流程：Friend 消息 → 仅使用人设提示词

1. src/types/textInputTypes.ts

- 在 QueuedCommand 中添加 overrideSystemPrompt?: string 字段，用于存储替代系统提示词

2. src/skills/bundled/friendPrompt.ts

- 导出 loadPersona() 和 buildVrmSystemPrompt()，供 FriendService 调用

3. src/friend/FriendService.ts

- 在 sendText() 中构建 VRM 人设提示词，作为 overrideSystemPrompt 随消息入队

4. src/utils/handlePromptSubmit.ts

- 在 onQuery 类型中添加 overrideSystemPrompt 参数
- 从 commands[0] 提取并传递给 onQuery

5. src/screens/REPL.tsx

- onQuery 和 onQueryImpl 均接收 overrideSystemPrompt 参数
- 传入 buildEffectiveSystemPrompt()，当该值存在时完全替代默认系统提示词

数据流

FriendService.sendText()
→ buildVrmSystemPrompt() ← 只构建 VRM 人设提示词
→ enqueue({ overrideSystemPrompt, ... })
→ processQueueIfReady()
→ handlePromptSubmit()
→ executeUserInput()
→ onQuery(..., overrideSystemPrompt)
→ onQueryImpl(..., overrideSystemPrompt)
→ buildEffectiveSystemPrompt({ overrideSystemPrompt })
→ 返回 [overrideSystemPrompt] ← 完全绕过 ~900 行 VersperClaw CLI 提示词

现在 /friend 模式下的消息只会使用人设提示词（VRM 情绪工具指令 + IDENTITY.md + SOUL.md），不再注入 VersperClaw
的编程助手系统提示词。
