Add test coverage and TODO.md log for the full temporal-cycle sweep

Extends tests/hours/matins.test.ts's proof-date table to cover all 28
newly-authored temporal ids end-to-end, including Easter and Pentecost
Sunday. Documents the full sweep in TODO.md, including the
easter-sunday/pentecost-sunday misdiagnosis and correction so the
"1 nocturn in the source" vs. "no content" distinction doesn't get
re-litigated later.
