/**
 * Popup-side copy helper.
 *
 * MV3 service workers can't reliably write the clipboard from a non-focused
 * tab — the SW path's `chrome.scripting.executeScript` into the active tab
 * loses the popup's user gesture and the page document is not focused, so
 * `navigator.clipboard.writeText` rejects with NotAllowed. The popup itself
 * is a focused document with a fresh user gesture and `clipboardWrite`
 * permission, so it can call the API directly. We then notify the SW with
 * `alreadyWritten: true` so it skips its own write and only schedules the
 * auto-clear timer.
