• Update removal logic to use specific regex patterns for injection formats, ensuring idempotent upgrades and preventing accidental removal of unrelated scripts.

Fix for #3 ?

Add authentication requirement

Introduces a 'Requires Authentication' option for scripts, allowing scripts to be loaded only for authenticated users. Updates the configuration UI to support the new option, splits script loading into public and private endpoints, and updates the injection logic to load scripts accordingly.

Support multiple scripts and dynamic injection

Add support for multiple scripts and dynamic injection

This is a complete rewrite of the plugin.
