Reading plans now track a cross-plan activity log for streaks, surface a
combined "today's reading" view on both Home and the Reading Plans page,
and let custom plans be edited after creation (including narrowing a book
to a specific chapter range). The reader auto-marks a plan's day read after
a dwell period, active plans that fall behind their pace get a "catch me
up" banner, and a new Settings section wires up daily reading reminders
via ntfy.sh, checked once a minute by a small server-side scheduler.
