/**
 * adowire client — adowire:poll directive
 *
 * Periodically calls `component.$refresh()` on the owning [adowire:id]
 * component at a configurable interval. Mirrors Livewire's wire:poll behaviour.
 *
 * Attribute value formats:
 *   adowire:poll              → 2000ms (default)
 *   adowire:poll="2s"         → 2000ms
 *   adowire:poll="500ms"      → 500ms
 *   adowire:poll="10s"        → 10000ms
 *
 * Behaviour:
 *   - Polling is paused while the tab is not visible (`document.hidden`).
 *   - Polling stops when the component's root element leaves the DOM.
 *   - A WeakMap prevents double-registration when the MutationObserver fires
 *     on the same element more than once.
 *   - `registerPollDirective()` is idempotent — safe to call multiple times.
