feat(rokt): add kit API parity access

[thomson-t]

Background

The Rokt kit migration for 6.0 moved partner-facing Rokt APIs out of the core SDK, but Kotlin consumers still need a low-friction way to access the kit facade from the active mParticle instance. The Rokt SDK Compose wrapper also exposes native placement events that were not forwarded through the mParticle kit wrapper.

What Has Changed

• Add Kotlin MParticle.rokt extension access for the Rokt kit facade.
• Keep the Java-friendly MParticleRokt.Rokt() helper as the supported Java entry point.
• Forward RoktLayout onEvent callbacks to the native Rokt SDK composable.
• Add tests for the Kotlin extension facade and stale instance refresh behavior.
• Update the Rokt kit README and changelog with the restored API shape.

PR Summary

Low Risk
Scoped Rokt kit API and Compose callback plumbing with tests; no auth, security, or core SDK behavior changes.

Overview
Restores ergonomic Rokt kit access after the 6.0 move of partner APIs out of core: Kotlin apps can call MParticle.getInstance()?.rokt, while MParticleRokt.Rokt() stays the Java entry point. Facade caching now tracks the active MParticle instance so a swapped singleton does not keep serving a stale Rokt object.

The Compose RoktLayout wrapper gains an optional onEvent callback wired through to the native Rokt SDK composable. README (6+ dependency), changelog, and unit tests cover the extension and instance-refresh behavior.
