    feat: Add -Yfuture-lazy-vals for Scala 3.3.x builds
    
    Motivation:
    The Scala 3.3.8 compiler introduced the -Yfuture-lazy-vals flag to
    optionally use VarHandle instead of sun.misc.Unsafe for lazy val
    implementation. This prepares libraries for upcoming JDK releases
    that restrict sun.misc.Unsafe access.
    
    Modification:
    Add -Yfuture-lazy-vals to scalacOptions, conditionally applied only
    for Scala 3.3.x via CrossVersion.partialVersion or scalaBinaryVersion.
    
    Result:
    Scala 3.3.x build uses the future-proof VarHandle-based lazy val
    implementation, compatible with all JDK 9+ versions including future
    releases that restrict sun.misc.Unsafe.
