How is the automatic memory cleanup mechanism in the system triggered?

In Go, the automatic memory cleanup mechanism (garbage collector, GC) is triggered automatically during program execution. It runs in parallel with the main thread, tracking objects in memory that are no longer used, and freeing them. The GC is triggered based on several factors, including the amount of allocated memory and a usage threshold, which is configurable within the runtime. Programmers can indirectly influence the GC by calling runtime.GC(), but this is usually not necessary, as the collector works efficiently on its own.
