hermes - 💡(How to fix) Fix feat: Support ANTHROPIC_BASE_URL environment variable in AIAgent

Problem

AIAgent constructor does not read ANTHROPIC_BASE_URL environment variable. Users cannot automatically use third-party endpoints (like cc.freemodel.dev) when setting this env var.

Current Behavior

Users must explicitly pass base_url to AIAgent constructor. ANTHROPIC_BASE_URL is ignored.

Expected Behavior

Support reading ANTHROPIC_BASE_URL as fallback:

if base_url is None:
    base_url = os.environ.get("ANTHROPIC_BASE_URL", "")
self.base_url = base_url or ""

Use Case

export ANTHROPIC_BASE_URL="https://cc.freemodel.dev"
export ANTHROPIC_API_KEY="fe_oa_..."
claude --print --bare -p "Use AIAgent"

Suggested Fix Location

run_agent.py around line 1284, before self.base_url = base_url or ""
