chore(release): v1.34.4 — one question, one answer

Every fix in this release is the same shape underneath. Two places in the code
were each deciding something they both had to agree on, and nothing made them
agree: two copies of the due-day rule, two clocks on one card, two server caches
behind one page, two ideas of where a nap belongs.

The version anchors, the changelog and the published specification move together
as usual.
