Invalidate the Android title measurement when the row or typography changes.

androidTitleLineHeight initializes once and stores only a number. Recycling can leave the previous row's measurement in state. A baseFontSize or fontScale change can leave the previous typography measurement in state. The stale value controls the project-icon height and status/provider minHeight until a new layout callback runs.

Store the measurement with the current row identity and effective typography inputs. Fall back to the current estimate when they differ. This also prevents a delayed callback from an older row from restoring stale state.

Suggested fix 
   const { width: windowWidth, fontScale } = useWindowDimensions();
   const titleTypography = useScaledTextRole("body");
   const metadataTypography = useScaledTextRole("label");
   const projectIconSize = titleTypography.fontSize * 1.25 * fontScale;
   const machineIconSize = metadataTypography.fontSize * fontScale;
+  const rowIdentity = `${thread.environmentId}:${thread.id}`;
+  const estimatedTitleLineHeight = titleTypography.lineHeight * fontScale;
   // Android's nonlinear system text scaling can differ from the fontScale estimate.
-  const [androidTitleLineHeight, setTitleLineHeight] = useState(
-    titleTypography.lineHeight * fontScale,
-  );
+  const [androidTitleMeasurement, setAndroidTitleMeasurement] = useState<{
+    readonly rowIdentity: string;
+    readonly fontSize: number;
+    readonly lineHeight: number;
+    readonly fontScale: number;
+    readonly measuredHeight: number;
+  } | null>(null);
   const titleLineHeight =
-    Platform.OS === "android" ? androidTitleLineHeight : titleTypography.lineHeight * fontScale;
+    Platform.OS === "android" &&
+    androidTitleMeasurement?.rowIdentity === rowIdentity &&
+    androidTitleMeasurement.fontSize === titleTypography.fontSize &&
+    androidTitleMeasurement.lineHeight === titleTypography.lineHeight &&

+      ? androidTitleMeasurement.measuredHeight
+      : estimatedTitleLineHeight;
...
-  const rowIdentity = `${thread.environmentId}:${thread.id}`;
   const [boundIdentity, setBoundIdentity] = useState(rowIdentity);
...
                   const firstLine = nativeEvent.lines[0];
                   if (firstLine && Math.abs(firstLine.height - titleLineHeight) > 0.5) {
-                    setTitleLineHeight(firstLine.height);

Review comment at @apps/mobile/src/features/threads/thread-list-v2-items.tsx
around lines 640 - 645:
Update the Android title-height state and layout callback in the thread-list row
to store each measurement with the current row identity and effective typography
inputs: font size, line height, and font scale. Use the measured height only
when those values match the current row and typography; otherwise use the
current estimated line height, so delayed callbacks for older rows cannot
restore stale measurements.
