feat(layout): grace-28 preset — 12 + 12 + inner ring of 4

[pyramation]

Summary

Grace Cathedral got three more lasers (25 → 28). New preset grace-28 keeps the two rings of twelve exactly as in grace-cathedral (indices 1–24 unchanged, so venue numbering and BEYOND mapping still hold) and replaces the centre dot with a ring of four at radius 0.25 (indices 25–28, a diamond at 12/3/6/9 o'clock).

'grace-28': () => ringsLayout({
  rings: [
    { count: 12, radius: 1, phase: 15 },
    { count: 12, radius: 0.62 },
    { count: 4, radius: 0.25 }
  ], ...
})

grace-cathedral is left untouched. Also added a "Grace 28" layout filter in the animation catalog and listed the preset in the CLI README. Test checks count, that fixtures 0–23 sit at the same positions as grace-cathedral, and that the four centre fixtures are ring 0 at radius 0.25.

🟠 High — Catalog test omits new grace-28 filter

This PR adds the grace-28 entry to layoutFilters() (packages/animations/src/catalog.ts:161), but packages/server/__tests__/catalog.test.ts still asserts the old four-element id list, so the toEqual check fails once the change lands. The adjacent consumer touch-points were updated consistently, but this server catalog test was missed; the failure blocks CI.

This PR introduces a grace-28 layout preset built on ringsLayout, combining a 12-cannon outer ring, a 12-cannon mid ring (positions 1-24 preserved from grace-cathedral), and a 4-cannon centre ring at radius 0.25. The preset is registered in presets.ts, exposed via layoutFilters() in catalog.ts:161, documented in the CLI README, and covered by a new layout config unit test.

The catalogue and consumers were updated consistently, but one consumer, the server catalog test, was missed: adding the new filter makes layoutFilters() return five ids while packages/server/__tests__/catalog.test.ts:54 still asserts the old four-element list, so the toEqual assertion fails and blocks CI.
