### What changes were proposed in this pull request? This PR adds `-Xcheckinit` to Spark's Scala compiler options for both SBT and Maven builds. ### Why are the changes needed? `-Xcheckinit` instruments Scala code to detect reads of uninitialized vals at runtime. This helps catch problematic initialization-order patterns, such as eager trait initializers reading subclass fields before those fields have been initialized. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Not run. This is a build configuration change. `git diff --check` ### Was this patch authored or co-authored using generative AI tooling?
