feat: switch to Claude Haiku 4.5 and add tool debug logging

Updated model from gpt-oss-120b (no function calling support) to
anthropic/claude-haiku-4.5 which has excellent function calling support
for enabling Morgan's agent creation tool.

Changes:
- Update OPENROUTER_MODEL to anthropic/claude-haiku-4.5
- Add debug logging to show available tools for each agent
- Claude Haiku 4.5 provides fast, cost-effective function calling

This enables tool calling for Morgan's create_agent_package functionality.
