* fix(translator): filter nameless hosted tools when converting Responses API to Chat format
Codex CLI sends "hosted" tools (e.g. `request_user_input`) via the OpenAI
Responses API. These tools have no explicit `name` field. The previous
`body.tools.map()` pass propagated `name: undefined` into the resulting
Chat Completions function declarations, which then became anonymous
`functionDeclarations` after the OpenAI→Gemini translation step.
Gemini strictly requires every function declaration to have a valid name
and rejects the entire request with:
GenerateContentRequest.tools[0].function_declarations[4].name:
Invalid function name. Must start with a letter or an underscore.
Fix: filter out any Responses API tool that lacks a non-empty `name`
string before converting to `{ type: "function", function: { name, ... } }`.
Named function tools are unaffected; only unnamed hosted tools are skipped.
Fixes: Gemini 400 error when Codex CLI is routed through 9router.

* feat(gemini): convert OpenAI SSE to Gemini SSE format in /v1beta/models route
The @google/genai SDK always uses :streamGenerateContent?alt=sse for chat
and expects Gemini SSE chunk format. The upstream handleChat returns OpenAI
SSE format, causing the SDK to crash on the [DONE] sentinel.
Changes:
- Add transformOpenAISSEToGeminiSSE() using TransformStream that converts
each OpenAI SSE chunk (choices[0].delta) to Gemini SSE format
(candidates[0].content.parts) on the fly
- Drop the OpenAI [DONE] sentinel (Gemini SSE ends by stream close)
- Map finish_reason -> finishReason, attach usageMetadata on final chunk
- Support reasoning_content -> thought: true parts for thinking models
- Refactor finishReasonMap to shared FINISH_REASON_MAP constant
- Fix streaming dispatch: stream=true now calls transformOpenAISSEToGeminiSSE
instead of passing OpenAI SSE through raw
Fixes: SyntaxError: "[DONE]" is not valid JSON in Gemini CLI
