WSaiOS v3 — 驱动系统内核（Driver Kernel）
? v3本质
v3 = 引入 Driver Model（驱动模型），让系统可以挂载外部能力（Device / IO / Service）
? v2 → v3 核心升级
| 层级 | v2 | v3 |
|---|---|---|
| 执行 | 并发任务 | 并发任务 |
| 核心能力 | Scheduler + Worker | + Driver System |
| 系统能力 | 内部计算 | 外部连接 |
| 扩展性 | 低 | 插件化（关键?） |
? v3工程结构（可运行）

v3新增核心抽象：
? Driver = 外部能力接口
系统不再“只执行任务”，而是：
✔ 调用驱动
✔ 连接外部系统
✔ 执行 IO 操作
✔ 插件化扩展能力

? WSaiOS v3 Driver Kernel Starting...
? Execution Results:
Worker-0 => [PRINT DRIVER] Hello WSaiOS
Worker-1 => [STORED] Save this data
Worker-2 => {'status': 200, 'response': 'API processed: Fetch user info'}
Worker-0 => [PRINT DRIVER] System OK? v3本质（非常关键）
? v3真正变化不是并发，而是：
1️⃣ Driver Model诞生（OS级核心?）
系统开始支持：
- 插件
- 外部能力
- IO扩展
2️⃣ Task → Capability Mapping
任务不再是“代码”，而是：
“调用某种能力”
3️⃣ 系统第一次连接外部世界
- storage
- api
? v3一句话定义
? v3 = 一个支持驱动插件（Driver Model）的并发执行内核，使系统具备外部IO能力
? v1 → v3 本质跃迁
v1 = 执行器
v2 = 并发调度器
v3 = 可扩展驱动系统（OS雏形）? 下一步（非常关键）
如果继续：
? v4：资源管理系统（真正OS核心）
- memory model
- storage filesystem abstraction
- resource allocator
