feat(sdk): support per-request timeout to TCP/QUIC/WebSocket clients

[chengxilo]

Which issue does this PR address?

Closes #3419

Rationale

Clients had no deadline on individual request, so a stalled server could block a caller forever.

What changed?

send_raw would be blocked forever if server doesn't response. I added a request_timeout field (IggyDuration, default 300s) to TcpClientConfig, QuicClientConfig, and WebSocketClientConfig. Each client's send_raw now wraps its I/O in tokio::time::timeout

Change Log
