fix: use-after-free in Lua garbage collection of shared objects (#3553)

This fixes a critical use-after-free issue caused by the premature
destruction of SharedObject instances managed via std::shared_ptr during
Lua’s __gc finalization.

Previously, the luaGarbageCollection function called reset() directly on
the shared pointer, which could destroy the underlying object while it
was still in use by C++ code — potentially leading to heap corruption
and runtime crashes.
