Fix Agno examples for v2 API compatibility

📥 Pull Request

📘 Description

This PR fixes 4 out of 5 failing Agno example files reported in #1266 by updating them to be compatible with Agno v2 API changes:

1. Team API updates (agno_basic_agents.py, agno_research_team.py):

   • Removed deprecated mode parameter from Team initialization (v1 API used mode="coordinate" or mode="collaborate")
   • Removed other deprecated Team parameters: success_criteria, enable_agentic_context, add_context, show_tool_calls
   • Moved members to be the first positional argument per v2 API signature

2. Import fixes (agno_workflow_setup.py):

   • Replaced RunResponse with RunOutput throughout (import, type hints, instantiation)
   • Updated all 5 occurrences across the file

3. Dependency correction (requirements.txt):

   • Changed duckduckgo-search to ddgs (the actual package name required by agno.tools.duckduckgo)

🧪 Testing

• Verified examples no longer crash with Team.__init__() got an unexpected keyword argument 'mode' error
• Confirmed agno_basic_agents.py runs to completion without import/API errors
• Verified agno_workflow_setup.py runs without ImportError: cannot import name 'RunResponse'
• Checked that ddgs is the correct package by inspecting agno's DuckDuckGoTools implementation

⚠️ Known Limitations

The telemetry validation issue mentioned in the original issue (#1266) for agno_async_operations.py (and affecting other examples) where token usage shows as 0 is NOT addressed in this PR. This appears to be a separate instrumentation issue that warrants its own investigation. The examples now run without crashing, but the validation checks still fail due to missing LLM token metrics.

🔍 Review Checklist

Please verify:

• [ ] The removed Team parameters are actually deprecated in Agno v2.x (I verified via inspect.signature(Team.__init__) but not against official docs)
• [ ] RunOutput is the correct replacement for RunResponse in Agno v2 API
• [ ] The ddgs package is the intended dependency (vs duckduckgo-search)
• [ ] Examples run successfully with actual API keys end-to-end
