fix: allow Anthropic API URLs as custom OpenAI-compatible endpoints

Browse source 
Removed the hard block on base_url containing 'api.anthropic.com'.
Anthropic now offers an OpenAI-compatible /chat/completions endpoint,
so blocking their URL prevents legitimate use. If the endpoint isn't
compatible, the API call will fail with a proper error anyway.

Removed from: run_agent.py, mini_swe_runner.py
Updated test to verify Anthropic URLs are accepted.
