feat(ffi): unwind safety: shield FFI entrypoints with panic guard (#546)

mirror of https://github.com/microsoft/regorus.git synced 2026-08-05 02:16:11 +00:00

This PR implements widely accepted Rust programming practices for
dealing with panics across ABI (programming language) boundaries.

- Add panic_guard.rs to wrap FFI calls and prevent panic across FFI/ABI boundary (undefined behavior).
- Capture per-thread backtraces via a temporary panic hook
- After a panic, subsequent invocations are poisoned.
- Integrate with_unwind_guard across the engine, schema registry, and target registry exportis
