Cargo build scripts bake JVM library search paths into native/target. Restoring that directory across CI jobs can reuse paths from a previous JDK installation, causing libjvm link failures after setup-java installs a different JDK. Keep caching the Cargo registry and git dependencies, but let each job rebuild target artifacts against its current JAVA_HOME. Co-authored-by: Codex <codex@openai.com>

Which issue does this PR close?
Part of #4248
Rationale for this change
Nested struct casts currently unwrap nested cast results while building the output
StructArray. When a nested cast fails, such as an ANSI overflow inside a struct, that unwrap can panic instead of returning the cast failure as a normal DataFusion error.What changes are included in this PR?
DataFusionResultinstead of unwrapping.How are these changes tested?
Updated tests suites and added native UTs.
