Fix Android and iOS KMP API parity, empty-byte handling, handler behavior, and runtime version metadata. Harden standalone native interop and Maven Central publication, add smoke tests and publishing documentation, and validate the published package on a physical iPhone.
KMP module at KMP/ exposes a Kotlin-idiomatic API in commonMain (com.tencent.mmkv.kmp),
with platform-specific implementations:
- androidMain: delegates to the existing com.tencent:mmkv Java library
- darwinMain: uses Kotlin/Native ObjC interop with the MMKV CocoaPod
Includes a Compose Multiplatform sample app (KMP/sample/) that demonstrates
MMKV initialization, encode/decode for all primitive types, named instances,
and key management on both Android and iOS.
