Makes any <select> with many options searchable, for web apps whose
dropdowns have no search. The original <select> stays in the DOM and
remains the source of truth: choosing an option sets selectedIndex and
fires native input/change events, so the host application and its form
submission are unaffected.
Handles option lists that the app repopulates at runtime via a per-select
MutationObserver, and new selects appearing after AJAX via a document-level
one. Filtering is substring-based, accent-insensitive and multi-token.
Built into both a Tampermonkey userscript and a bookmarklet from one source.
