Add malloc_log_dump() to print all recorded malloc/free/realloc calls with their addresses, sizes, and caller information. This provides a way to inspect the log after recording. The dump shows a summary line with entry counts, followed by a table with sequence number, operation type, pointer, size, and caller for each recorded operation.
