feat: new build tools

[arzola]

This pull request modernizes and streamlines the Excalibur plugin's frontend build and asset management workflow. It migrates from Laravel Mix to Vite (via pressbooks-build-tools), updates Node and PHP requirements, restructures asset locations, and updates related code to use the new frontend tools package. These changes improve maintainability, developer experience, and compatibility with current tooling.

Build system and tooling migration:

• Replaces Laravel Mix with Vite for asset building, introducing a new vite.config.js and removing webpack.mix.js; updates NPM scripts and dependencies in package.json to use pressbooks-build-tools v5, and switches Node engine requirement to v22.

• Updates PHP requirement to 8.2 and replaces pressbooks/mix with pressbooks/frontend-tools in composer.json. ([composer.jsonL19-R21](https://github.com/pressbooks/excalibur/pull/91/files#diff-d2ab9925cad7eac58e0ff4cc0d251a937ecf49e4b6bf57f8b95aab76648a9d34L19-R21))

Asset structure and import updates:

• Moves source JS and SCSS files to assets/src/, updates imports to use new locations, and ensures SCSS uses the modern @use syntax. ([[1]](https://github.com/pressbooks/excalibur/pull/91/files#diff-d200670db798b35491a753c7a65a6cd41558cbd6738aa74544c30d6daae034e9R1-R2), [[2]](https://github.com/pressbooks/excalibur/pull/91/files#diff-7668d6b1e4a3d543aaf07495a243074801df66c4a57e28b8b01d2b141d1fb9e5L1-R1))
• Updates asset enqueuing in inc/class-admin.php to use the new PressbooksFrontendTools\Assets and AssetType, and to enqueue the built JS bundle correctly. ([[1]](https://github.com/pressbooks/excalibur/pull/91/files#diff-7ea4b51e842a1863ff86582979e64534421f4b306842e009fd33edb7bc46541aL6-R7), [[2]](https://github.com/pressbooks/excalibur/pull/91/files#diff-7ea4b51e842a1863ff86582979e64534421f4b306842e009fd33edb7bc46541aL26-L31))

These changes collectively bring the plugin's frontend workflow in line with current Pressbooks standards and best practices.
