Adds js/druid.behaviors.js with a heavily-commented Drupal.behaviors
skeleton, registered as the druid/behaviors always-on library (depends
on core/drupal and core/once). The IIFE is empty — ready for the first
behavior. CLAUDE.md gains a JavaScript section so future work has the
same self-documenting entry point as the CSS architecture.
Separately, removes 12 Adelle .otf source files that were committed
alongside their .woff2 web versions; only .woff2 is referenced from
css/fonts.css, so the .otf copies were ~1.4 MB of unreferenced bytes.
