Pull Request Overview

This PR adds new utility modules for generating random environment values and managing temporary resource changes, expands package exports, reorganizes tests, updates project dependencies, and fixes a guard in config parsing.

• Introduce random_generators.py for creating mock Discord tokens, guild IDs, webhook URLs, and organisation IDs.
• Add context_managers.py with context managers for deleting environment variables, temporary file removal, and settings replacement.
• Update __init__.py, adjust pyproject.toml dependency groups and lint rules, remove deprecated tests, add a focused test for generate_invite_url, and guard against None in config.py.

utils/random_generators.py:1

• The new random value generators currently lack dedicated unit tests. Add tests to verify that generated tokens, IDs, and URLs match expected patterns and constraints.

"""Module for generating random values for environment variables."""

utils/context_managers.py:1

• Context managers for environment variable deletion, settings replacement, and file deletion are not covered by tests. Consider adding unit tests to ensure they properly delete, restore, and handle edge cases.

"""Module containing context managers for temporary deletions and replacements."""
