/**
* Initializes tab navigation

* - Tab buttons: <button data-tab="system">System</button>
* - Tab panels: <div data-tab-panel="system">...</div>
* - Container: <div data-tabs>...</div>
* - URL param: ?tab=system
* Initializes tab navigation with chevron-based overflow scrolling.
*
* Markup (author writes):
* <div data-tabs>
* <div class="app-tabs-nav">
* <button data-tab="system" data-tab-default>System</button>
* ...

*
* JS wraps the nav in `.app-tabs-nav-wrap` and injects chevron buttons when
* the strip overflows. No-JS fallback: native horizontal scrollbar stays.
