* feat: Add dual output support to Agent component with structured JSON parsing
## Summary
- Add "Structured Response" output alongside existing "Response" output
- Filter out conflicting json_mode field from OpenAI inputs
- Implement robust JSON parsing with fallback handling
## Changes Made
### Agent Component (agent.py)
- Add second output: "Structured Response" (Data type) with tool_mode=False
- Filter json_mode from OpenAI inputs to prevent UI conflicts
- Add json_response() method with multi-stage JSON parsing:
- Direct JSON parsing for valid responses
- Regex extraction for embedded JSON in text
- Graceful error handling with diagnostic info
- Share execution between outputs (no duplicate agent runs)
- Fix model building to handle missing json_mode attribute
### Tests (test_agent_component.py)
- Add 9 comprehensive test cases covering:
- Dual output structure validation
- Input filtering verification
- JSON parsing (valid, embedded, error cases)
- Model building without json_mode
- Shared execution efficiency
- Frontend node structure
- Component initialization
## Benefits
- Users get both Message and Data output types to choose from
- Clean UI without confusing duplicate JSON toggles
- Robust JSON parsing handles various response formats
- Efficient single-execution approach
- Maintains backward compatibility

* chore: update webrtcvad dependency and add optional audio support
- Updated webrtcvad version requirement to >=1.9.4 in pyproject.toml and uv.lock.
- Moved webrtcvad to optional dependencies under the new 'audio' category in both pyproject.toml files for better modularity.
- Ensured compatibility with existing dependencies while enhancing documentation for optional audio features.
* fix: handle optional import of voice_mode_router in API initialization
- Updated the API router initialization to conditionally include the voice_mode_router if it is available, improving modularity and preventing import errors.
- Adjusted the import statement for voice_mode_router to handle ImportError gracefully, ensuring the application remains robust in its absence.
* feat: add voice mode flag to API configuration
- Introduced a new function `get_voice_mode_enabled` to check for the availability of the `webrtcvad` library, enhancing the API's capability to support voice mode features.
- Updated the `ConfigResponse` schema to include `voice_mode_enabled` flag, allowing clients to query the status of voice mode support.
- Integrated the voice mode feature flag into the `get_config` endpoint response, improving the configurability of the API.
* test: skip voice mode tests if webrtcvad is not installed
- Added a conditional import for the webrtcvad library in the voice mode test suite.
- Implemented a pytest marker to skip tests when webrtcvad is unavailable, enhancing test robustness and preventing unnecessary failures.
* feat: add voice mode state management to flows manager store
- Introduced `voiceModeEnabled` state and `setVoiceModeEnabled` action in the flows manager store to manage the voice mode feature.
- Updated the `ConfigResponse` interface and `useGetConfig` hook to integrate the new voice mode state, allowing for dynamic configuration updates.
- Enhanced the API's configurability by ensuring the voice mode state is properly set based on the API response.
* feat: conditionally render voice button based on voice mode state
- Integrated `voiceModeEnabled` from the flows manager store to control the visibility of the VoiceButton component.
- The VoiceButton will now return null if voice mode is not enabled, enhancing the user interface by preventing unnecessary rendering.
* fix: ensure boolean conversion for voice mode state in config hook
- Updated the `setVoiceModeEnabled` function in the `useGetConfig` hook to explicitly convert the `voice_mode_enabled` value to a boolean, ensuring consistent handling of the voice mode state based on API responses.
* refactor: conditionally import voice_mode_router in API initialization
- Updated the API router to conditionally include the voice_mode_router based on its availability, enhancing modularity and preventing import errors.
- Adjusted the __init__.py file to dynamically add voice_mode_router to the __all__ list if the import is successful, improving the API's robustness.

Here is an optimized version of your program.
**Reasoning for changes:**
- The check `isinstance(custom_component, Component)` followed by `type(custom_component) is not Component` causes the interpreter to potentially look up the type and MRO twice per call.
- By storing `type(custom_component)` in `klass` and using `issubclass(klass, Component)`, you avoid having Python walk the MRO twice for the same object, which is subtly more efficient especially in tight loops and heavy use scenarios.
- Using `issubclass()` on the object's type is semantically equivalent to `isinstance()`, except it also works for custom metaclass scenarios and is very slightly faster when type is already known.
**All program logic and comments are preserved, only the relevant portion is optimized.**

Updated function names for converting inputs to Message, Data, and DataFrame types to improve readability and consistency. The changes include renaming `get_message_converter` to `convert_to_message`, `get_data_converter` to `convert_to_data`, and `get_dataframe_converter` to `convert_to_dataframe`. Additionally, added a check for dictionary input in the data conversion function.
* fix: add TYPE_CHECKING for conditional imports in message.py
Introduced TYPE_CHECKING to optimize imports for the DataFrame type, ensuring that the import only occurs during type checking. This change enhances performance and maintains compatibility with static type checkers.
* refactor: simplify data conversion methods in Message class
Removed unnecessary parameters from the `to_data` and `to_dataframe` methods in the Message class, enhancing clarity and reducing complexity. The methods now directly use instance attributes, improving code readability and maintainability.
* refactor: enhance DataFrame methods for clarity and type safety
Updated the `to_data` and `to_message` methods in the DataFrame class to improve clarity and type safety. The `to_data` method now directly converts the DataFrame to a Data object without parameters, and the `to_message` method uses the instance's data directly. Added TYPE_CHECKING for conditional imports to optimize performance and maintain compatibility with static type checkers.
* refactor: streamline Data class methods for improved clarity
Refactored the `to_message` and `to_dataframe` methods in the Data class to eliminate unnecessary parameters and directly utilize instance attributes. This change enhances code readability and maintainability while ensuring type safety with the appropriate imports for Message and DataFrame. Additionally, updated the logic to access instance data more intuitively.
* refactor: simplify conversion method calls by removing redundant arguments
* rename test file
* refactor: remove obsolete test file for data conversion
* refactor: add support for converting dictionary to DataFrame
