Convert getDescriptionsForTemperature to createMemo for reactive updates

[Copilot]

getDescriptionsForTemperature was a plain function called once at render time, meaning SolidJS never tracked tempAvg() as a dependency — description sets wouldn't update when the signal changed.

Changes

• vroce.tsx: Wrap getDescriptionsForTemperature in createMemo so SolidJS tracks tempAvg() and recomputes the correct description set reactively

// Before: called once, no reactive tracking
const getDescriptionsForTemperature = () => {
  const avg = tempAvg();
  if (avg != null && Number.isFinite(+avg) && +avg < 30) return opisi_pod_30;
  return opisi;
};

// After: recomputes whenever tempAvg() changes
const getDescriptionsForTemperature = createMemo(() => {
  const avg = tempAvg();
  if (avg != null && Number.isFinite(+avg) && +avg < 30) return opisi_pod_30;
  return opisi;
});

Pull request overview

This pull request fixes a reactivity bug in the temperature description display by converting a plain function to use SolidJS's createMemo. Previously, getDescriptionsForTemperature was called once at component render time, preventing it from tracking changes to the tempAvg() signal. Now it properly recomputes when the temperature changes.

Changes:

• Wrapped getDescriptionsForTemperature in createMemo to enable reactive tracking of tempAvg()
• Added createMemo import from "solid-js"
