Sean Murphy 35c021b2a3 feat(opencode): add opencode_go and opencode_zen first-class providers ... Adds OpenCode Zen and OpenCode Go as first-class LiteLLM providers, each serving three wire formats: Chat Completions, Anthropic Messages, and OpenAI Responses. Routing between the three arms is decided in code, not from the runtime cost map, because a published map predating this provider would send every Messages-native model down the wrong wire. The model sets carry the full forward-looking grid of model names so a gateway-side addition routes correctly without a release; names without a bundled price simply stay unpriced until a real one is published. Cost resolution falls back to pricing bundled with the package when the runtime cost map carries no usable entry -- the Router registers a bare placeholder for every deployment at startup, so the guard asks for pricing the cost calculator can actually use, not for the key's presence. The cost-map JSON schema gains a `messages` mode so the new entries validate, and the provider tests set module-level configuration through monkeypatch rather than writing process-wide globals directly.		2026-09-12 19:06:07 -07:00
