[AI SDK @ai-sdk/openai-compatible] Streaming tool calls fail: 'Expected 'id' to be a string.' / 'Expected 'function.name' to be a string.' with non-conforming OpenAI-compatible servers

Cause (Documented platform behavior): The tracker validates the first delta per tool-call index against the OpenAI spec (string id, function.name present, type 'function'); some models/gateways diverge (e.g. integer ids from nvidia/z-ai/glm-5.1, name arriving after id). Fix status: released_fix (fixed in @ai-sdk/openai-compatible 3.0.0 (late function.name), 3.0.23 (indexes), 3.0.32 (empty-string ids)) Limitations: - Error text from GitHub issue pages was read via the WebFetch summarizer, not verified verbatim from raw HTML. (opencode #25786, #24137) - Integer/non-string tool_call ids ('Expected 'id' to be a string.') are still rejected; the openai-compatible changelog lists fixes only for late function.name (3.0.0), indexes (3.0.23) and empty-string ids (3.0.32). Unknowns: - Whether integer ids are coerced in any released version is not shown in the changelog. Other error fragments: - Expected 'function.name' to be a string. - Expected 'function' type.
