* fix: DeepSeek temperature defaulting to 0 instead of 0.3
Pass defaultTemperature: DEEP_SEEK_DEFAULT_TEMPERATURE to getModelParams() in
DeepSeekHandler.getModel() to ensure the correct default temperature (0.3)
is used when no user configuration is provided.
Closes#11194
* refactor: make defaultTemperature required in getModelParams
Make the defaultTemperature parameter required in getModelParams() instead
of defaulting to 0. This prevents providers with their own non-zero default
temperature (like DeepSeek's 0.3) from being silently overridden by the
implicit 0 default.
Every provider now explicitly declares its temperature default, making the
temperature resolution chain clear:
user setting → model default → provider default

When the 'custom base URL' checkbox is unchecked in the UI, the setting
is set to '' (empty string). Providers that passed this directly to their
SDK constructors caused 'Failed to parse URL' errors because the SDK
treated '' as a valid but broken base URL override.
- gemini.ts: use || undefined (was passing raw option)
- openai-native.ts: use || undefined (was passing raw option)
- openai.ts: change ?? to || for fallback default
- deepseek.ts: change ?? to || for fallback default
- moonshot.ts: change ?? to || for fallback default
Adds test coverage for Gemini and OpenAI Native constructors verifying
empty-string baseURL is coerced to undefined.
* fix(ai-sdk): preserve reasoning parts in message conversion
* fix(ai-sdk): convert message-level reasoning_content to reasoning part
* fix(task): remove invalid openai-compatible from reasoning allowlist
* feat: add isAiSdkProvider() method for dynamic AI SDK provider detection
- Add isAiSdkProvider() method to ApiHandler interface
- Default implementation in BaseProvider returns false
- Override to return true in 11 AI SDK providers:
deepseek, fireworks, mistral, groq, xai, cerebras,
sambanova, huggingface, gemini, vertex, openai-compatible
- Update Task.ts to use dynamic detection instead of hardcoded Set
- Add method to FakeAIHandler and update test mocks
* fix: handle reasoning parts in flattenAiSdkMessagesToStringContent
- Strip reasoning parts when flattening messages for string-only models
- Allow flattening when message contains only text and reasoning parts
- Add tests for reasoning part handling in string-only model contexts
This addresses the review feedback about ensuring flattenAiSdkMessagesToStringContent
works correctly when reasoning parts are present (e.g., SambaNova DeepSeek).
