Pull request overview

This PR fixes a JavaScript string translation issue that prevented translation plugins like Loco Translate from discovering and translating JS strings in the Carousel Kit WordPress plugin. It adds the wp-cli/i18n-command tooling and commits a generated .pot file containing all translatable strings from both PHP and compiled JS sources.

Changes:

• Adds wp-cli/i18n-command as a Composer dev dependency and a pot script for generating the .pot file
• Commits the auto-generated languages/carousel-kit.pot file containing all translatable strings (PHP and JS)
• Updates composer.lock with the new dependency and transitive dependency version bumps
