Add 5 example actor configurations demonstrating all actor types:
Simple Examples:
- simple_llm.yaml: Basic LLM actor with code review prompt
- llm_with_tools.yaml: LLM with mix of tool references and inline tools
- tool_collection.yaml: Tool-only actor (no LLM)
Graph Examples:
- simple_graph.yaml: 3-node linear workflow (extract → analyze → summarize)
- graph_workflow.yaml: Complex TDD workflow with 10 nodes
* Conditional routing based on test results
* Retry logic with max attempts
* Subgraph composition (code review)
* Error escalation paths
Each example demonstrates:
- Proper namespaced naming (namespace/name)
- Type-specific configurations
- Context and memory settings
- Environment variable usage
- Tool definitions (inline and references)
