feat: Add dual output support to Agent component with structured JSON parsing (#8836)
* 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
