actop 1.4.13

Changed

• Mem BW and Package Power charts/alerts now normalize against a session
  ratchet: max(calibrated_reference, highest_observed_this_session). Both
  denominators are best-effort per-chip guesses (Apple doesn't publish exact
  bus-bandwidth or power-limit specs); a real sample above the guess raises
  the effective ceiling permanently for the session (increase-only — a later
  lower sample never lowers it back), so the chart self-corrects toward the
  true physical ceiling instead of silently saturating against an
  under-calibrated static guess. AlertEngine.feed() computes both ratchets
  via a small private _Ratchet helper and returns them as two new
  AlertFrame fields (effective_max_bw, effective_max_package_w) — the
  engine's one existing output contract — so the chart and its alert always
  read the same ratcheted value from the same frame.
