fix: address bot review feedback on tool metadata

- Use `is not None` instead of truthiness check so empty tools list
  is sent to the API rather than being silently dropped as None
- Strip __init__ suffix from module path for tools in __init__.py files
- Extend _unwrap_schema to handle function-before, function-wrap, and
  definitions wrapper types
