WebKit's WKWebView rejects top-level const/let declarations that shadow
global function names. Since utils.js defines functions like stateLabel()
at the global scope (non-module scripts), and later files destructure
the same names from window.NexusTerminal using const, WebKit throws:
SyntaxError: Can't create duplicate variable that shadows a global property
Fix: wrap every JS file in an IIFE so all declarations are function-scoped.
Also remove temporary diagnostic instrumentation.
Replace ES module import/export with a global namespace pattern to avoid
silent failures in the Wails v2 WKWebView which does not reliably support
<script type="module"> tags.
- Remove all import/export statements from JS files
- Register each module's exports on window.NexusTerminal
- Destructure dependencies from window.NexusTerminal at file top
- Load all scripts in dependency order in index.html as plain <script> tags
