Add reflective fallback for useK2 to support Kotlin 2.3.0+

[jstewart5000]

Summary

This PR adds a defensive getUseK2Value helper to handle the removal of useK2 in Kotlin 2.3.0+.
In newer Kotlin versions, the getUseK2() property no longer exists, causing reflective lookups to fail.
To ensure forward compatibility, the new method attempts to read useK2 via reflection when available, and safely falls back to the Kotlin 2.3.0+ default behavior (useK2 = true) when the property or its provider cannot be accessed.

• Uses reflection to read useK2 only when the property exists (older Kotlin versions).
• If reflection fails, logs the reason and defaults to true.
• Prevents crashes related to missing getUseK2() in Kotlin 2.3.0+.
