feat: add curl options to prevent stuck connections

Add three curl options to the Guzzle client to prevent connections from
getting stuck indefinitely:

1. Low-speed stall guard (CURLOPT_LOW_SPEED_LIMIT + CURLOPT_LOW_SPEED_TIME):
   Fails requests if transfer speed drops below 1 byte/sec for 120 seconds

2. Disable connection reuse (CURLOPT_FORBID_REUSE + CURLOPT_FRESH_CONNECT):
   Prevents reusing stale keep-alive connections that may be half-closed

3. TCP keepalive (CURLOPT_TCP_KEEPALIVE + CURLOPT_TCP_KEEPIDLE + CURLOPT_TCP_KEEPINTVL):
   Enables TCP-level keepalive to detect dead connections
