* fix(sse): project non-streaming JSON back to the Gemini/Antigravity envelope
The streaming and non-streaming response paths disagreed on how a response is
projected back into a non-OpenAI client's wire format.
Streaming goes through the translator registry, where the
FORMATS.OPENAI -> FORMATS.ANTIGRAVITY translator
(open-sse/translator/response/openai-to-antigravity.ts) projects each OpenAI
chunk into the `{ response: { candidates: [...] } }` envelope, mapping
tool_calls to `functionCall` parts and reasoning to `thought` parts.
The non-streaming path uses translateNonStreamingResponse() instead. Its
"Phase 3: translate back to client source format" step only special-cased
FORMATS.CLAUDE — every other non-OpenAI client format fell through and returned
the raw OpenAI chat.completion intermediate. A Gemini/Antigravity client issuing
a non-streaming request therefore received `choices[]`/`tool_calls` instead of
`candidates[]`/`functionCall`: the client's parser sees no candidates and the
function calls are effectively dropped, so tool-calling silently breaks on the
JSON path while working over SSE.
Adds convertOpenAINonStreamingToGeminiFamily() and wires it into Phase 3 for
FORMATS.GEMINI / FORMATS.ANTIGRAVITY, mirroring the shape the streaming
translator already emits so both paths agree. Tool-call `arguments` are parsed
through a non-throwing helper: a provider emitting truncated JSON degrades that
call's args to `{}` rather than raising an uncaught SyntaxError in the shared
response hot path (matching the streaming translator's behaviour).
Scoped deliberately narrow: only the Gemini-family projection gap proven by the
failing test is closed. The Ollama/Responses projections and the SSE terminal
tracker from the upstream change are not ported — OmniRoute has no OLLAMA format
in FORMATS, and its Responses/[DONE] handling already lives in
nonStreamingSse.ts + the registry.
