/**
 * Avatar Module — Talking-Head / Lip-sync Integration for NeuroLink
 *
 * Provides avatar-generation capability across providers (D-ID, HeyGen,
 * Replicate-hosted MuseTalk / SadTalker / Wav2Lip).
 *
 * Use `AvatarProcessor.generate(provider, options)` to dispatch to the
 * registered handler for `provider`.
 *
 * Importing this module does NOT register any handlers as a side effect.
 * Call `registerDefaultAvatarHandlers()` explicitly (or go through
 * `ProviderRegistry.registerAllProviders()`, which every documented
 * `NeuroLink` entry point already calls) to register every shipped avatar
 * handler whose backing API key is present in `process.env`. Registration
 * is idempotent and silently skipped if a provider is already registered or
 * its constructor throws.
 *
 * @module avatar
