Module agent 

Agent runtime - the core orchestration loop.

The agent coordinates between:

• Provider: Makes LLM API calls
• Tools: Executes tool calls from the assistant
• Session: Persists conversation history

The main loop:

1. Receive user input
2. Build context (system prompt + history + tools)
3. Stream completion from provider
4. If tool calls: execute tools, append results, goto 3
5. If done: return final message
