feat: add initial agents module with graph structure and templates

- Introduced the agents module with a new graph-based architecture, including Front and Back graphs.
- Added base classes for nodes and graphs, enhancing modularity and scalability.
- Created scaffold templates for agents, including pyproject.toml and README files.
- Implemented state management and node execution logic for both Front and Back graphs.
- Included integration and unit tests to ensure functionality and reliability.
- Added environment configuration examples and pre-commit setup for code quality management.
