PingerPlot 1.1.1 — performance.

A focused speedup of the live UI. The 700 ms refresh was doing ~30 ms of pure-Python stats work each tick — holding the GIL against the probe threads — which made the app feel sluggish, and worse the more targets you watched. Now ~2–3 ms.

  • Per-hop stats (loss / avg / min / max / jitter) are computed in a single pass instead of ~5 — snapshot() ~4× faster, the sidebar grid ~97× faster with several targets.
  • The sidebar reads only the destination hop's stats instead of every hop of every monitor.
  • Redundant canvas redraws are skipped on ticks where nothing changed (resize / tab-switch still redraw).

No feature or behavior changes. 75 tests green on Windows + Linux, Python 3.10–3.13.
