Pull request overview

This PR hardens the Rust FFI boundary for execution by catching panics during owasm_vm::run, and updates the crate/dependency versions and CI artifact actions to align with the new release.

Changes:

• Wrap owasm_vm::run in catch_unwind in do_run to prevent panics from unwinding across the FFI boundary.
• Bump libgo_owasm crate version and the owasm-vm dependency to 0.3.2.
• Update GitHub Actions artifact upload/download steps from @v3 to @v4.
