v1.10.0

• Accept the relative dates people actually type. Anywhere a date is taken —
  capture, propose, due, schedule, defer, the TUI edit form, and the
  API — two weeks, in two weeks, and two weeks from now all work, in
  digits or English number words, over seconds, minutes, hours, days, weeks,
  months, or years. Calendar units also take compact forms: 2d, 2w, 2m
  (months), 2y. Second-, minute-, and hour-relative phrases produce a timed
  value from the current instant; since stored times have minute precision, a
  result carrying seconds rounds up so it never lands earlier than the
  boundary that was asked for. Such a phrase already names an exact side of a
  DST overlap, so pairing it with --fold is refused rather than silently
  resolved. next week/next month/next year keep working as the one-unit
  spellings.
• Make releasing one command: BUMP=major|minor|patch make release derives the
  version from the latest tag, stamps ## [Unreleased] with the version and
  date, commits release: prepare vX.Y.Z, pushes main, and publishes — the
  version is stated once. RELEASE_VERSION=vX.Y.Z make release and a hand-
  stamped heading still work; make release-dry-run prints the plan, verifies
  the Homebrew publication prerequisites, and stops before any mutation. Every
  existing fail-closed publication check is unchanged.
