• Introduced automatic tree integrity check: check_tree_integrity().
• Expanded serialization capabilities: get_tree(), get_tree_json(), load_tree_json(), load_tree().
• Support for new interfaces for import/export, autocomplete, CRUD and search.
• Added Django-compatible unittest tests for automatic CI/CD checking.

Added

• treenode/admin/{exporter, importer, mixin}.py — new modules for extended work in the admin panel.
• treenode/models/models.py — new main container of the tree model.
• treenode/utils/db/ — new subsystem for low-level SQL logic and compatibility with various DBMS.
• treenode/views/* — modular structure of views (autocomplete, search, api).
• treenode/settings.py — default configuration with customization support.
