chore: update project configuration and documentation

- Added *.egg-info/ to .gitignore to prevent egg metadata from being tracked.
- Updated virtual environment instructions in CONTRIBUTING.md and README.md to use .venv for consistency.
- Revised mkdocs.yml to include a placeholder for the repository URL when publishing.
- Cleaned up pyproject.toml by removing unnecessary pylint configuration.
- Enhanced import-format.md and runbook.md documentation for clarity on user roles and health check endpoints.
