also using IPC to proxy requests now

[Copilot]

Pull Request Overview

This PR migrates the funcd runtime from a TCP-based HTTP reverse proxy architecture to an IPC-based (Unix socket) proxy designed for AWS Lambda. The implementation removes WebSocket and SSE support, simplifies the runtime to focus on basic HTTP proxying, and adds Lambda response streaming capabilities.

• Replaced axum-based HTTP reverse proxy with reqwest Unix socket client for IPC communication
• Migrated to lambda_http and lambda_runtime for AWS Lambda integration
• Added response streaming support with configurable toggle
