stabeyandClaude Opus 5.5 75bc32cfe9 fix(formats): repair live cross-format conversion gaps
Verified against a live Antigravity + xAI deployment:

- Gemini and Claude clients calling a forced-stream Responses upstream
  (xAI, Codex) without streaming always failed: the aggregated body echoes
  request metadata (parallel_tool_calls, tools, encrypted reasoning) that
  the strict cross-format check refuses, and the gateway then wrapped the
  raw SSE capture in a client error body sent with HTTP 200. Project the
  validated aggregate to every client format, as the Chat path already
  does, and return 502 instead of raw provider bytes when a successful
  cross-format response still cannot be converted.
- Gemini stream decoding keyed tool calls by part position, so parallel
  calls arriving in separate chunks (all at parts[0]) merged into one call
  with concatenated arguments. Key them by arrival order; ids cannot be
  used because they are optional and the Antigravity envelope synthesizes
  per-chunk ids that repeat across chunks. Generated call_auto_N ids now
  follow arrival order.
- Non-stream Responses output reported truncated or filtered cross-format
  answers as completed; derive incomplete + incomplete_details from the
  canonical stop reason.
- Gemini request parsing ignored parametersJsonSchema and
  responseJsonSchema and passed OpenAPI upper-case type names (OBJECT,
  STRING) through to JSON Schema targets, which xAI rejects.
