Introduce a provider registry so the managed-agent client can route to an Anthropic-compatible endpoint. Adds MiniMax (MiniMax-M3, global_en/cn_zh regional base URLs) alongside the existing default provider, selected via INFERENCE_PROVIDER/PROVIDER_REGION. Default behaviour is unchanged.

Reason: The gateway hard-wires a single bare inference client and model, so there is no abstraction to route the agent through the MiniMax provider.
What changed
gateway/src/providers.ts: a small inference-provider registry. Each entry declares its default model, API-key environment variable, and any regional Anthropic-compatible base URLs. The existing default provider and MiniMax are registered.gateway/src/config.ts: resolve the provider fromINFERENCE_PROVIDER(default preserves today's behaviour) andPROVIDER_REGION, and expose the resolved base URL, API-key env name, and a provider-aware default forAGENT_MODEL. Warns when the selected provider's API key is missing.gateway/src/cma.ts: build the shared client with the resolved base URL and API key so the same@anthropic-ai/sdkclient reaches the selected provider's endpoint. When no override is set the client behaves exactly as before.gateway/.env.example: documentINFERENCE_PROVIDER,PROVIDER_REGION, andMINIMAX_API_KEY.MiniMax exposes an Anthropic-compatible endpoint, so it is reached through the existing client by overriding
baseURL— no second SDK is added. Selectingminimaxdefaults the model toMiniMax-M3and targetshttps://api.minimax.io/anthropic(global) orhttps://api.minimaxi.com/anthropic(cn_zh).Checks
npm cinpm run typecheck(tsc --noEmit) — passesminimaxresolves toMiniMax-M3with the global endpoint,cn_zhresolves to the regional endpoint, and unknown provider/region values fall back with a warning.
