refactor(tools): static import → require() 迁移 + 兜底修复

Codex 完成:
- tools.ts: 7 个 static import (指向空壳 stub) → require("@claude-code-best/builtin-tools/...")
  涉及: SleepTool, CronTools, RemoteTriggerTool, MonitorTool, SendUserFileTool,
  PushNotificationTool, TeamCreateTool, TeamDeleteTool, SendMessageTool, WorkflowTool
- PermissionRequest.tsx: MonitorTool require() 指向 builtin-tools
- TeamCreateTool/DeleteTool/SendMessageTool 用 lazy require() 打破循环依赖

兜底修复:
- defines.ts: 保持 MONITOR_TOOL + WORKFLOW_SCRIPTS 禁用
  原因: builtin-tools 里的真工具 import "src/..." 产生跨包循环引用
  在 splitting:true 下触发 chunk 间死锁，在 splitting:false 下触发 ESM 初始化死锁
  这是逆向工程的结构性限制，非简单修复能解决

验证: --version / -p / --print / 源码模式 全部通过
