- Replaced synchronous file reading with asynchronous file handling using aiofiles in multiple handlers and the backup module.
- Improved performance and responsiveness when sending images and backups by utilizing async file operations.
- Ensured consistent use of BufferedInputFile across all relevant functions for better code maintainability.
- Consolidated and simplified code formatting by removing unnecessary line breaks and improving readability in various functions.
- Updated the handling of backup file sending in backup.py for better clarity.
- Streamlined error handling and logging messages in several handlers to enhance consistency.
- Adjusted the Makefile to exclude specific files during Ruff checks and formatting.
- Made minor adjustments to function signatures and parameter handling for improved clarity and consistency.
This commit enhances code maintainability and readability without altering functionality.
