v3.13.5 — →NN% projection relearns after an official re-baseline

Fixed

• The →NN% projection relearns after an official re-baseline instead of
  freezing for the rest of the window. The sample recorder refused any
  same-window reading at or below the recorded max — meant to filter stale
  session replays, but those are already gated upstream by the reconcile merge
  (v3.13.3/v3.13.4). After Anthropic re-baselined the weekly limit (19% → 3%),
  no new sample could be recorded until usage exceeded the old 19%, so the
  projection kept showing a pre-rebaseline →100% for days. A converged
  reading below the same-reset max now means the limit changed: all stored
  samples for that window are in old-denominator units and incomparable, so
  they're dropped, display smoothing restarts, and the projection relearns
  from the window's bucket priors onward.
