feat: implement dynamic version tracking and reporting system

- Add snapshotter/version.py module for centralized version management
- Update project version from 0.1.0 to 2.11.0
- Display version during Docker container initialization
- Use dynamic version in snapshot submissions instead of static config
- Add toml dependency for pyproject.toml parsing
- Ensure single source of truth for version information

This improves observability, debugging capabilities, and ensures accurate
version reporting across the Snapshotter network.
