Fixed two bugs in the HTTP server that could cause hangs:
1. web/chttp.c:4060 - Fixed incorrect error buffer check
- Was checking output buffer for errors after a read operation
- Should check input buffer instead
- This could cause the server to miss read errors and not close
bad connections properly
2. web/main.c:334 - Added loop to process multiple queued requests
- Previously only processed one request per event loop iteration
- Now processes all queued requests before returning to poll()
- This prevents requests from being stuck in the queue when the
socket is in ESTABLISHED_READY state
These fixes improve the server's ability to handle multiple requests
on Keep-Alive connections.
