AI Summary: The `ts-backend-check` tool is incorrectly deriving file paths relative to its installation directory, rather than the intended project root. This behavior is causing issues for users, specifically highlighted during work on activist/activist#1325, as it leads to incorrect path resolution within projects.

AI Summary: Implement rich color support in the ts-backend-check CLI output using the Rich library. This involves adding Rich as a dependency, modifying existing print statements to use Rich's `print` function, and styling success and error messages with green and red respectively.

AI Summary: Implement a feature in the `ts-backend-check` Python package to check for updates and provide an upgrade option via the CLI. This involves checking for newer versions using a suitable method (e.g., checking PyPI), notifying the user, and providing a command to upgrade using `pip`.

AI Summary: Implement a feature for the `ts-backend-check` CLI tool that allows users to specify multiple TypeScript type and backend model file pairs via a YAML configuration file, eliminating the need for repetitive command-line arguments. This involves parsing the YAML configuration, iterating through the specified file pairs, and running the type checking process for each pair.

AI Summary: Refactor the command-line interface (CLI) of the `ts-backend-check` Python package from using the Click library to using the argparse library. This is to improve consistency with the activist organization's `i18n-check` project.
