Subject: [PATCH] feat: add Gemini provider support

- Add gemini to PROVIDERS map with OpenAI-compatible endpoint
  (https://generativelanguage.googleapis.com/v1beta/openai)
- Add gemini to PROVIDER_ENV_VARS (reads GEMINI_API_KEY from env)
- Add gemini URL detection in inferProviderFromBaseUrl()
- Add gemini to AIBrain.BASE_URLS fallback map
- Fix localProvider not propagated in resolveApiConfig() return values
- Fix visionModel/textModel falling back to pipeline config layer3/layer2
  models when resolvedApi provides no model name (prevented empty model
  string being sent to the API)

No API keys are stored in source files.
Configure via env: GEMINI_API_KEY=your_key AI_BASE_URL=https://generativelanguage.googleapis.com/v1beta/openai
