/**
 * #3229 — agy `gemini-3.1-pro-high`/`-low` returned [400] but were MASKED as an empty
 * `chat.completion` envelope.
 *
 * Two parts:
 *  (a) the budget-suffix ids had no alias, so `resolveAntigravityModelId` sent them
 *      verbatim to upstream (which rejects -high/-low for gemini-3.x) → alias to plain.
 *  (b) the non-stream branch fed the 4xx response into the SSE collector, producing a
 *      synthetic `{"object":"chat.completion","content":""}` instead of a real error →
 *      build a proper sanitized error body for non-ok upstream responses.
