feat: Detect incorrect multi-threaded use from c based ffi (#499)

Browse Source 
Add runtime detection for shared handle misuse

wrap the FFI engine handle with parking_lot::RwLock when the new
contention_checks feature is enabled, surfacing a clear “handle is already
in use” error instead of allowing undefined behavior
keep the feature optional so no_std builds or environments that supply
their own synchronization can opt out
caution users that this guards the handle itself but does not make the
engine’s operations globally thread-safe on its own
