What is meant by the phrase "except that bowing (rukūʿ) and prostration (sujūd) are performed" in the context of describing the Prophet’s prayer of eight rakʿahs on the Day of the Conquest of Makkah, and does this differ from normal prayer?

What is meant by her statement in the Hadith: "The bowing and prostration are perfected" is the perfection of tranquility and the recitation of the remembrances within them. This is because the Prophet, peace and blessings be upon him, lightened all other pillars except for tranquility in bowing and prostration, in order to dispel any notion that the lightening might imply a deficiency in bowing and prostration.
