/**
 * @oxpulse/chat-widget — Product picker (seller catalog).
 *
 * Searchable dropdown listing the seller's product catalog. On select,
 * calls `onSelect(productRef, productMeta)` which the Composer wires to
 * `setProductCard()`.
 *
 * Lifecycle (mirrors EmojiPicker):
 *   show(anchorEl)  — appends picker to container, positions below anchor
 *   hide()          — removes from DOM, restores focus
 *
 * A11y:
 *   role="dialog", search input focused on open, Arrow keys navigate,
 *   Escape hides + restores focus, Tab focus trap.
 *
 * Used from:
 *   - Composer: product button in the toolbar → opens picker →
 *     onSelect → composer.setProductCard(ref, meta) → existing chip → send
