* fix: updated ChatOutput component not working with streaming enabled (#6744)
fixes: 69df913a14
Updated to handle the forgotten Generator case for self.input_value (encountered when streaming is enabled).
Overhauled the chat.py under outputs to (mostly) pass strict type checking, something which could have prevented this bug.
Only this file has been changed. The only type errors in this file are in the safe_convert function and are due to problems in other files.
To prevent further problems in the future, the project should work towards enabling strict type checking permanently after fixing the vast number of type problems.

- Updated platform markers from 'sys_platform' to 'platform_system' for better compatibility in uv.lock, affecting multiple packages including 'jinxed', 'colorama', and 'appnope'.
- Ensured consistency in platform checks across various dependencies to enhance cross-platform support.
This update improves the project's dependency management and ensures better compatibility across different operating systems.
* feat: Enhance ResultDataResponse serialization with truncation support
- Introduced a new method `_serialize_and_truncate` to handle serialization and truncation of various data types, including strings, bytes, datetime, Decimal, UUID, and BaseModel instances.
- Updated the `serialize_results` method to utilize the new truncation logic for both individual results and dictionary outputs.
- Enhanced the `serialize_model` method to ensure all relevant fields are serialized and truncated according to the defined maximum text length.
This update improves the handling of large data outputs, ensuring that responses remain concise and manageable.
* fix: Reduce MAX_TEXT_LENGTH in constants.py from 99999 to 20000
This change lowers the maximum text length limit to improve data handling and ensure more manageable output sizes across the application.
* test: Add comprehensive unit tests for ResultDataResponse and VertexBuildResponse
- Introduced a new test suite in `test_api_schemas.py` to validate the serialization and truncation behavior of `ResultDataResponse` and `VertexBuildResponse`.
- Implemented tests for handling long strings, special data types, nested structures, and combined fields, ensuring proper serialization and truncation.
- Enhanced coverage for logging and output handling, verifying that all fields are correctly processed and truncated as per the defined maximum text length.
- Utilized Hypothesis for property-based testing to ensure robustness and reliability of the serialization logic.
This update significantly improves the test coverage for the API response schemas, ensuring better data handling and output management.

* Qwen/Qwen2.5-Coder-32B-Instruct
* Qwen/QwQ-32B-Preview
* openai-community/gpt2
* custom option
- Add real_time_refresh to model_id dropdown for dynamic updates
- Implement custom model input field that shows/hides based on selection
- Replace temperature FloatInput with SliderInput for better UX:
* Added RangeSpec with min=0, max=2, step=0.01
* Maintains default value of 0.8
- Add build_config update logic to handle custom model visibility
- Update API URL generation to support custom model IDs
- Import RangeSpec and SliderInput from langflow packages

This commit updates the test suite to verify the new features and changes in
the HuggingFace component, ensuring proper functionality of the model selection
dropdown and improved temperature control.
Key changes in src/backend/tests/unit/components/models/test_huggingface.py:
- Update test_huggingface_inputs to verify new DropdownInput for model_id:
* Check DEFAULT_MODEL as default value
* Verify presence of 'custom' option
* Validate required and real_time_refresh settings
- Add verification for custom_model field:
* Confirm initial custom_model hidden state
* Verify required flag
- Add specific checks for temperature SliderInput:
