SAMHandlerPool (Javadocs [I2P+ 2.13.0+]

```
class SAMHandlerPool
extends Object
```
Shared NIO selector-based handler pool for SAM v3 control connections. Replaces the thread-per-connection model for SAM v3 handlers with a single selector thread reading all handler sockets and dispatching complete command lines inline. Commands are processed serially per-connection in the order they arrive. PING/PONG keepalive and idle timeout are handled at the pool level so individual handlers do not consume threads while waiting for input.
