/**
 * EventValidator - Client-side validation of tracking events against the Avo Tracking Plan.

 * - Pinned values (exact match required)
 * - Allowed values (must be in list)
 * - Regex patterns (must match pattern)
 * - Min/max ranges (numeric values must be in range)
 *
 * No schema validation (types/required) is performed - only value constraints.
 * Validation runs against ALL events/variants in the response.
