Streams LLM responses and tool executions using the Anthropic Messages API.

This generator function orchestrates the complete agent-tool interaction loop:

1. Builds system prompt (static or dynamic) from agent definition
2. Streams LLM response chunks, yielding text-delta events
3. Detects tool calls and yields tool-call-start events
4. Parses tool arguments and yields tool-call-args events
5. Optionally waits for approval via approval-required/waitForApproval
6. Executes tools via dependencies.executeToolWithGuards
7. Yields tool-call-result or tool-call-error events
8. Continues conversation with tool results until completion or max iterations

Supports extended thinking (reasoning-delta events) and lifecycle hooks (onToolCall, onToolResult). All infrastructure errors are retried via dependencies.withInfrastructureRetry.
