Run prettier formatter to fix code style issues

[Copilot]

This PR runs the prettier formatter across the codebase to ensure all files conform to the project's code style standards.

Changes

The prettier formatter identified and fixed a minor code style issue in .prettierrc.js:

• Added a trailing comma to the last item in the overrides array, following JavaScript best practices

Verification

All files now pass prettier's formatting checks:

yarn prettier --check .
# ✓ All matched files use Prettier code style!

This ensures consistent code formatting across the repository and prevents future linting failures.

Original prompt

run the prettier formatter
