When the user's config uses a non-Anthropic provider with an
Anthropic-compatible endpoint (e.g. MiniMax at
https://api.minimax.io/anthropic), chat in the WebUI fails silently
with APIConnectionError on every request, while the hermes CLI and
messaging gateway work fine with the same config.
Root cause: both api/routes.py and api/streaming.py constructed
AIAgent using only (model, provider, base_url) from
resolve_model_provider() and never passed api_key. When the base URL
ends in /anthropic, AIAgent uses the anthropic_messages adapter, but
only falls back to ANTHROPIC_TOKEN when provider == "anthropic" (a
safety check to avoid leaking Anthropic credentials to third parties).
For MiniMax and similar providers the effective key becomes "", and
the auth failure surfaces as a generic "Connection error" after three
retries.
The CLI and gateway resolve the key via
hermes_cli.runtime_provider.resolve_runtime_provider(), which reads
MINIMAX_API_KEY (and similar) from ~/.hermes/.env. This patch does the
same before creating the AIAgent in both chat paths.
