Bugfixes

• Default provider header timeouts to five minutes so slow model startups fail less often.
• Default streamed chunk timeouts to five minutes, with false supported to disable them.
• Let Anthropic thinking.blockBinding opt out via config when you need to keep the provider default. (@​dkindlund)
• Limit Anthropic thinking block binding to Claude 5.1+ models so older deployments do not reject requests.
• Avoid unhandled errors when canceling timed-out SSE reads. (@​AlexanderWillner)
