Don't commemorate a Vigil alongside the very feast it anticipates

At Vespers/Compline, a day's own Vigil losing tonight to tomorrow's First
Vespers was showing up as a redundant extra commemoration alongside that
same feast (e.g. Nov 29's Compline showing both "St. Andrew" and "Vigil
of St. Andrew" for Advent I's anticipated evening).

Added an explicit `vigilOf` field to each Vigil's own saint record
(several Vigil ids don't map cleanly to their feast's id by stripping a
`vigil-of-` prefix — `vigil-of-the-assumption` vs `assumption`,
`vigil-of-st-james` vs `st-james-the-greater` — so this needs to be
explicit rather than guessed from the id or date adjacency).
calendar/vespers.ts's evening-anticipation merge now skips adding the
Vigil commemoration when tomorrow's winner or its own commemorations
already include that same feast.
