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 Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com>
