Bug: The package.json scripts use the --ext flag with eslint, but this flag was removed in the newly upgraded ESLint v10, which will cause script failures.
_{Severity: CRITICAL}

Suggested Fix

Remove the --ext flag from all eslint commands in the package.json scripts. Create a new eslint.config.js flat configuration file to specify which files ESLint should process, replacing the functionality previously handled by the --ext flag.

Location: package.json#L57

Potential issue: The project has been upgraded to ESLint v10, which removes support for
the `--ext` command-line flag. However, the `test`, `lint`, and `lint-staged` scripts in
`package.json` still use the `--ext` flag. This will cause these scripts to fail at
runtime with an "Invalid option '--ext'" error, breaking local development and CI
workflows like testing, linting, and committing code.
