Fix privileged-feria-major: nothing is ever commemorated, any rank

The Easter octave cascade built last commit reused the existing
"duplex-majus+ still gets a bare commemoration" branch unchanged,
trusting its own citation (St. Mark within the Easter Octave). That
citation was a misreading. Live-verified: the Annunciation (Duplex I.
classis) transfers with zero commemoration on Holy Thursday itself, and
Chair of St. Peter at Antioch does the same on Ash Wednesday - the
exception was wrong everywhere this category is used, not just Holy
Week. privileged-feria-major now matches privileged-sunday exactly:
unconditional transfer, no exceptions, any rank.
