refactor(drivers): organize backup modules into drivers subfolder
lint / docker (push) Has been cancelled
lint / docker (push) Has been cancelled
- Move all backup_*.py files to libtisbackup/drivers/ subdirectory - Move XenAPI.py and copy_vm_xcp.py to drivers/ (driver-specific) - Create drivers/__init__.py with automatic driver imports - Update tisbackup.py imports to use new structure - Add pyvmomi>=8.0.0 as mandatory dependency - Sync requirements.txt with pyproject.toml dependencies - Add pylint>=3.0.0 and pytest-cov>=6.0.0 to dev dependencies - Configure pylint and coverage tools in pyproject.toml - Add conventional commits guidelines to CLAUDE.md - Enhance .gitignore with comprehensive patterns for Python, IDEs, testing, and secrets - Update CLAUDE.md documentation with new structure and tooling Breaking Changes: - Drivers must now be imported from libtisbackup.drivers instead of libtisbackup - All backup driver files relocated to drivers/ subdirectory 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
