- Introduced a new `renovate.json` file to manage dependency updates.
- Configured automerge settings for various dependency types, including Python packages and development tools.
- Set up labels for better categorization of dependencies and defined rules for specific file names and package names.
- Enabled dependency dashboard and immediate PR creation for updates.
