The agenda widget loaded and sliced its data in the provideGlance preamble
and captured it as a non-reactive local. updateAll() reliably recomposes a
live Glance session but does not reliably re-run that preamble, so a range
change was redrawn against the stale slice (intermittently — only when no
session was alive did it pick up the new range). This is the same platform
limitation the month widget already works around.
Mirror that pattern: load the widest selectable window once, store the range
in per-instance Glance state (AGENDA_RANGE_KEY), read it reactively via
currentState, and slice in the composition. The settings setter writes the
state into each instance and recomposes, so a range change now reflects via
plain recomposition regardless of session lifecycle.
