**Summary**

Adds consent-management support across the Optimization SDK Suite and documents how applications should map privacy policy decisions into SDK behavior.

- Adds split consent handling for event emission vs durable profile continuity with `consent({ events, persistence })`, while preserving boolean `consent(true | false)` as a shorthand for both.
- Exposes `states.persistenceConsent`, adds `PERSISTENCE_CONSENT_KEY`, and gates profile, anonymous ID, selected optimization, and changes persistence behind persistence consent.
- Refactors stateless Core/Node event calls behind `forRequest(...)`, so each request binds consent, profile, shared event context, and Experience options before calling `page`, `identify`, `trackView`, etc.
- Updates Web, React Web, React Native, iOS, Android, and the native JS bridge to restore profile continuity only when permitted, clear durable continuity when denied, and support split consent APIs.
- Updates hybrid Node/Web and Next.js reference implementations to use application-owned consent cookies, render baselines before consent, and persist shared anonymous IDs only when continuity consent allows it.
- Adds a cross-SDK consent concept guide and refreshes package READMEs/guides with default-on, strict opt-in, split-consent, revocation, and server/browser alignment guidance.
- Expands test coverage for consent gating, storage restore/clear behavior, request-bound stateless calls, native storage, and baseline-before-consent flows.

**Notable API/behavior changes**

- New/updated exports include `ConsentInput`, `CoreStatelessRequest`, request-scoped stateless types, `EventType`, `PERSISTENCE_CONSENT_KEY`, and `states.persistenceConsent`.
- Node/stateless direct event methods now use `forRequest(...).page()/identify()/...`.
- Core now fails closed by default; platform SDKs provide their runtime-specific pre-consent allowlists.
