Fix rememberViewStore autoClose ownership

[hkusu]

Summary

• apply autoClose per remembered Store instead of fixing it once per rememberViewStore call
• document the close ownership behavior in rememberViewStore KDoc
• add JVM tests for same-Store recomposition and key-based Store replacement

Why

• keep disposal ownership stable for the same Store across recompositions
• let a newly remembered Store pick up the current autoClose value after a key change

Verification

• JAVA_HOME=/Users/h_kusu/Library/Java/JavaVirtualMachines/AndroidStudio/Contents/Home ./gradlew :koma-compose:jvmTest --tests io.github.komakt.koma.compose.ViewStoreJvmTest
