- Call initializeLibrary() (setupForeignThreadGc) in the `.ffi.` request
wrapper and in add/remove_event_listener so a foreign (Go) caller thread
has an initialised Nim heap before any allocation ($reqTypeName /
$eventName / registry ops). Without it such a thread segfaults in the
allocator under GC pressure — the production unwrap SIGSEGV.
- recycleContext resets the event registry/queue + stuck flag on park so a
reused pool slot starts clean.
- ffiDtor doc/cleanup for the async recycle ABI.

* protect against mem leak in case of failures sending requests to ffi thread
* better cleanup if failures in createFFIContext
* avoid dangling cstring in handleRes under ARC/ORC
* better resource cleanup in destroyFFIContext
* invoke onNotResponding if failure in destroyFFIContext
* correct seq copy in alloc
* make sure the lock is init before cleanUpResources
* better possible exception handling in processReq
* guard allocSharedSeq if given seq is empty
* enhance error handling in ffi_context
* add new tests and some corrections
