/**
 * Collects behavioral biometric signals from user interactions.
 * Computes aggregate statistics from mouse, keyboard, scroll, session, and touch data.
 *
 * Design principles:
 * - All DOM listeners use `{ passive: true }` to avoid blocking the main thread
 * - High-frequency events (mousemove, scroll, touchmove) are throttled
 * - All statistics use Welford's online algorithm (O(1) memory)
 * - No raw event streams stored — only summary aggregates
 * - `collect()` returns pre-computed summaries; called by EventCoordinator on existing events
