docs: 优化Java NIO文档图解,使用Excalidraw可视化
- 将ASCII文字图替换为专业的Excalidraw图表
- 新增4个可视化图表:三大核心组件架构、Selector多路复用模型、Buffer核心属性、零拷贝原理对比
- 图表使用配色方案区分不同组件(蓝色-Channel, 绿色-Buffer, 橙色-Selector)
- 在Obsidian中可通过![[...]]语法直接嵌入查看

feat: add Netty and Java NIO interview questions
Added 3 comprehensive interview documents covering Netty and Java NIO:
**1. Netty Core Principles (Netty核心原理.md)**
- Core components: Channel, EventLoop, ChannelPipeline, ByteBuf
- Reactor threading model (single/multi-threaded, master-slave)
- ByteBuf vs Java NIO ByteBuffer
- Zero-copy implementation (4 approaches)
- ChannelPipeline and ChannelHandler
- TCP sticky/unpacking problem solutions
- Heartbeat mechanism
**2. Java NIO Core Principles (Java NIO核心原理.md)**
- NIO vs BIO comparison
- Three core components: Channel, Buffer, Selector
- Selector multiplexing mechanism
- Channel vs Stream differences
- Buffer core attributes and usage
- Non-blocking I/O implementation
- Zero-copy with transferTo and MappedByteBuffer
**3. Netty Practice Scenarios (Netty实战场景.md)**
- High-performance RPC framework design
- WebSocket server implementation
- Million-connection IM system architecture
- Memory leak detection and resolution
- Graceful shutdown implementation
- Heartbeat and reconnection mechanisms
Each document includes:
- Detailed problem descriptions
- Complete code examples (Java)
- Architecture diagrams
- Best practices
- Performance optimization tips
- P7-level bonus points
Total: 3 documents, covering:
- Theoretical foundations
- Practical implementations
- Production scenarios
- Performance tuning
- Common pitfalls
Suitable for backend P7 interview preparation.
