Closes #22. Closes Epic #14 (the temporal cycle Factory — the whole Proper of Time).

The final piece: the six movable feasts of the Lord that are placed by a Sunday rule rather than filled as part of a block.

What's here

MovableFeasts — forYear($year) places six feasts, each a white FEAST on its own date (feasts() / on()).

Feast	Placement	Class
Most Holy Name of Jesus	Sunday of 2–5 Jan, else 2 Jan	II
Holy Family	Sunday of 7–13 Jan (first after Epiphany)	II
Most Holy Trinity	Easter+56	I
Corpus Christi	Easter+60	I
Most Sacred Heart	Easter+68	I
Christ the King	last Sunday of October (1962)	I

Scope & accuracy

Issue #22 is framed around the three civil-anchored feasts that need the dedicated Sunday-placement rules — including the edge case it calls out: when no Sunday falls in 2–5 January, the Holy Name is kept on 2 January (tested via 2023, whose 1 January is a Sunday). The three Easter-anchored feasts are trivial PaschalSkeleton offsets, included so the movable temporal cycle is complete.

All six are feasts of the Lord → temporale, under the anchor family that computes them. They overlay the temporal skeleton the block-fillers emit (Trinity occupies the first-Sunday-after-Pentecost slot); composing them by precedence/commemoration is the resolver's job (#29).

Verified across a 1583–2200 sweep (proper weekdays and placement windows; 266 years exercise the Holy Name 2-Jan edge; six distinct dated observances). An adversarial review (with web verification of the 1962 dates, ranks, and Latin titles) raised no findings.
