feat(audience): add Audience class with consent, tracking, and identity

[ImmutableJeffrey]

Summary

Adds the Audience class to @imtbl/audience (renamed from @imtbl/audience-sdk) — the web SDK for consent-aware event tracking and player identity.

import { Audience } from '@imtbl/audience';

const audience = Audience.init({
  publishableKey: 'pk_imtbl_...',
  environment: 'production',
  consent: 'anonymous',
});

audience.page();
audience.track('purchase', { item: 'sword', price: 9.99 });
audience.identify('user@example.com', 'email', { name: 'Jane' });
audience.setConsent('full');
audience.shutdown();

What's included

• Audience.init() with track, page, identify, alias, setConsent, reset, flush, shutdown
• Three-tier consent model: none (inert), anonymous (no PII), full (all events)
• Auto-tracked session_start on new session, session_end on shutdown()
• Attribution capture: UTM params, click IDs, referrer, landing page — cached per session
• Uses core's createConsentManager, collectAttribution, and getOrCreateSession — no duplicated logic with pixel

De-duplication with #2830

• Deleted local attribution.ts, cookie.ts — now imports from @imtbl/audience-core
• Deleted custom ConsentController class — now uses core's createConsentManager (shared with pixel)
• Deleted consent-transport.ts — core's httpSend handles the PUT
• Collapsed web/ package into sdk/ per review feedback

Test plan

• cd packages/audience/sdk && pnpm test — 46 tests pass
• cd packages/audience/sdk && pnpm build — builds clean
