/**
 * Read scroll position and extents for either the document or a specific
 * scrollable element.
 *
 * - Without `selector`: returns `window.scrollX/scrollY` and document
 *   `documentElement.scrollWidth/Height - window.innerWidth/Height` (clamped
 *   to 0 for non-scrollable axes).
 * - With `selector`: returns `el.scrollLeft/scrollTop` and
 *   `el.scrollWidth/Height - el.clientWidth/Height` so callers can detect
 *   inner-viewport "scrolled to bottom" without falling back to `eval`.
 *
 * Mirrors the precedence already accepted by `electron_scroll_to_element` /
 * `electron_scroll_by_pixels` (which take an optional selector) — fixes #16
 * where the selector argument was silently stripped.
