Diego Rodrigues de Sa e Souza 62e6336aad fix(antigravity): alias agy gemini-3.1-pro -high/-low + stop masking upstream 4xx (#3229) (#3245) ...

agy's gemini-3.1-pro-high/-low had no alias, so resolveAntigravityModelId sent the
speculative -high/-low suffix verbatim to upstream, which rejects it (400) for
gemini-3.x. Worse, the non-stream executor branch fed the 4xx response into the SSE
collector, returning a synthetic empty {object:chat.completion} envelope that masked
the error. Alias both to gemini-3.1-pro, and surface real upstream errors via
buildErrorBody for non-ok non-stream responses. + unit tests.
