/**
 * ScrollToBottomCapturer
 *
 * Subscribes to scroll events from the chat store and triggers scroll-to-bottom
 * behavior when messages change, with support for scroll locking.
 *
 * How it works:
 * - Listens to `scrollToBottom$` Subject that emits whenever messages change
 * - Checks the current lock state from `scrollLocked$` BehaviorSubject
 * - Only scrolls if the scroll is NOT locked
 *
 * Scroll Locking:
 * - Use `lockScroll()` before loading older messages to prevent auto-scroll
 * - Use `unlockScroll()` after loading completes to restore normal behavior
 * - The lock prevents scroll during pagination, maintaining user's scroll position
 *
 * RxJS Pattern:
 * - `withLatestFrom` ensures we only emit when scrollToBottom$ fires (not when lock state changes)
 * - This prevents unwanted scrolling when unlocking; unlock itself won't trigger scroll
 * - `filter` blocks emissions when isLocked === true
