* feat(zai): fall back to BIGMODEL/ZHIPUAI api keys and add GLM-5.3 aliases and glm-5v-turbo
Resolve the zai api key from ZAI_API_KEY, BIGMODEL_API_KEY or ZHIPUAI_API_KEY
so deployments predating the zai rename keep working. Accept response_format
and max_completion_tokens as supported openai params. Register zai/GLM-5.3
and zai/GLM-5.3-Flash aliases plus the glm-5v-turbo vision model in both the
main and backup cost maps
* fix(zai): read only ZAI_API_KEY, dropping the BigModel key fallbacks
* fix(zai): map max_completion_tokens to max_tokens, correct glm-5v-turbo pricing, drop redundant aliases
* fix(zai): reject json_schema response_format, add glm-5v-turbo cache read price
* fix(zai): forward every response_format type so allowed_openai_params keeps working
* fix(zai): follow json_schema natively on glm-5.3, prompt other models, drop over-limit max_tokens under drop_params
* fix(zai): keep BigModel's json_schema as sent and never drop the caller's max_tokens under drop_params
* fix(zai): write the prompted JSON schema as JSON so models answer with valid JSON
* test(zai): type the zai provider tests and mark their locals Final

* feat: add BigModel provider with native Chat, Responses, and Messages APIs

* fix(bigmodel): keep the Coding Plan base, surface Responses auth errors, and scope routes
Chat Completions keeps a GLM Coding Plan api_base. Responses raises the status from
BigModel's success=false body instead of returning an empty 200, and a JSON body
answering a stream request is replayed as a one-shot stream. Messages streams keep
ping and [DONE] lines. bigmodel leaves openai_compatible_providers so speech, image,
and transcription routes send it no request
* fix(responses): replay a JSON body on a stream request only when it has a Content-Length
A gateway that labels a chunked SSE stream as application/json kept streaming before
the replay, so only a sized body is read in full
* fix(bigmodel): scope the JSON stream replay to BigModel, map its business error codes, and echo requested tools
* fix(bigmodel): forward Codex's include and parallel_tool_calls, keep the OpenAI org header off BigModel, and pass unchanged Messages stream events through
* fix(bigmodel): map disabled thinking to low effort, keep Messages temperature, raise context window and content policy errors, and default parallel_tool_calls to true
* fix(bigmodel): keep the caller's reasoning_effort when Messages rewrites disabled thinking
* fix(bigmodel): keep context-window and content-policy errors on streamed Responses replays
