refactor(buffer): Optimizes TCP and HTTP streaming request processing using a buffer pool.

Replaces the fixed-size buffers in `FrameHandler` and `Handler` with dynamic buffers obtained from the buffer pool,

to reduce memory allocation and improve performance. Also updates the logo path in the README to match the new resource directory structure.
