Pull Request Overview

This PR implements buffer pooling to reuse request buffers across the codebase, reducing memory allocations and garbage collection pressure. The changes introduce sync.Pool for managing reusable byte slices in protocol handlers and HTTP clients.

Key changes:

• Modified protocol handlers (Gemini, Gopher, Finger) to use pooled buffers instead of creating new allocations per request
• Updated HTTP client code in fed/send.go to return buffer data with cleanup callbacks instead of response objects
• Replaced bytes.Buffer with pooled []byte in LineWriter for more efficient buffer management
