Function gc_plugin_shutdown 

pub unsafe extern "C" fn gc_plugin_shutdown(instance: *mut c_void)

@brief Safely shuts down the plugin instance.

This function is invoked by the core to terminate the plugin instance. The following points should be taken into consideration regarding concurrency:

• After this function completes, no other functions exported by the plugin will be called for this instance.
• During the execution of gc_plugin_shutdown, other plugin functions may still be running concurrently if their calls were initiated before gc_plugin_shutdown was invoked. It is therefore the plugin’s responsibility to handle any potential race conditions while releasing resources.
• All resources allocated by the plugin should be released by the time this function returns.

@param instance A pointer to the plugin instance being shut down.
