Dual VoT 8.5.4 — Yandex player crash fix
Fixes the crash introduced with Morphe 1.49.0-dev.7, where changing player state could fail with NoClassDefFoundError: kotlin.Unit.
- Java player event callbacks no longer require Kotlin runtime classes.
- Legacy stable player events remain compatible through an isolated adapter.
- PiP observers are removed using the same registered listener object.
- Regression tests run with Kotlin entirely unavailable and cover legacy callbacks and listener removal.
The Morphe base for this stable release remains 1.48.0. Full Android bundle build, automation tests and focused runtime regression tests passed. The MPP manifest, archive integrity and license notices were checked. Android device confirmation is pending.
