通过 Databricks 连接模型服务

用户层 [model_providers.Databricks]，base_url 以 /ai-gateway/codex/v1 结尾，wire_api = responses。短时令牌走 [model_providers.Databricks.auth]，避免重复配置 env_key。

model_provider = "Databricks"

[model_providers.Databricks]
name = "Databricks AI Gateway"
base_url = "https://YOUR_WORKSPACE/ai-gateway/codex/v1"
wire_api = "responses"

[model_providers.Databricks.auth]
command = "sh"
args = ["-c", "databricks auth token --host YOUR_WORKSPACE --output json | jq -r '.access_token'"]
timeout_ms = 5000
refresh_interval_ms = 1800000
