Summary

• Add useDecideAsync, useDecideForKeysAsync, and useDecideAllAsync hooks — async counterparts to the existing sync decide hooks, required for CMAB, async UPS etc.

Test plan

• Add tests for all 3 new async hooks covering store states, race conditions, re-evaluation triggers, forced decision reactivity, and render optimization

Issues

• FSSDK-12296

[Copilot]

Pull request overview

Adds async counterparts to the existing “decide” React hooks so consumers can evaluate flags via the Optimizely SDK’s async decide APIs (needed for CMAB / async decisioning) while handling loading/error states, cancellation, and forced-decision reactivity.

Changes:

• Introduces useDecideAsync, useDecideForKeysAsync, and useDecideAllAsync and exports them from the public entrypoints.
• Adds shared useAsyncDecision state machine to manage async execution, cancellation of stale promises, and store readiness transitions.
• Adds comprehensive Vitest coverage for the 3 new hooks and extends hook test utilities with async decide method stubs.
