Update allowed tools configuration in SimpleClaudeRunner

- Removed environment variable dependency for allowed tools, setting a default list directly in the code.
- Ensured consistency in allowed tools across different methods within the SimpleClaudeRunner class.

This change simplifies the configuration process and maintains uniformity in tool availability.
