v0.8.0 - API Enhancements & Multi-Provider Support

✨ Features

API Enhancements

• Granular SSE Events: Real-time streaming with detailed events (thinking, plan, code_executing, code_result, answer, round_complete)
• /turns Endpoint: Structured conversation history for consistent UI rendering
• HITL API: Human-in-the-Loop support via REST endpoints (/hitl/status, /hitl/approve, /hitl/reject)
• Runtime Model Switching: Change LLM model mid-conversation via PUT /sessions/{id}

Multi-Provider Support

Added validation and documentation for:

• Groq (GROQ_API_KEY)
• Together AI (TOGETHER_API_KEY)
• OpenRouter (OPENROUTER_API_KEY)
• Mistral (MISTRAL_API_KEY)
• Cohere (COHERE_API_KEY)
• Perplexity (PERPLEXITYAI_API_KEY)
• Fireworks (FIREWORKS_API_KEY)
• Hugging Face (HUGGINGFACE_API_KEY)

🐛 Fixes

• Autonomous loop: Now stops correctly when plan is complete (no more infinite "next step" prompts)
• Config loading: Combined .env files - global (~/.dsagent/.env) + local (./.env) with proper override
• Summarization: Uses user's model by default (no longer requires OpenAI configured)

📚 Documentation

• Complete HTTP API reference for UI developers
• All supported LLM providers documented with API key variables
• Configuration guide updated with correct .env loading order

🔧 CI/CD

• Docker images now build only on releases (not on every push to main)
