Re-measure coverage, because the figure here was quoted from before the test push

CLAUDE.md's own rule is "re-measure before quoting", and the figure it carried
was measured on 2026-08-24 -- before the #52 children, the MediaProbe and codec
tests, and the guards from #100/#107 landed. Quoting it now would understate the
suite by twelve points, which is the same failure the bullet directly below it
was written to describe.

Measured on b53f326 with ./gradlew :app:jacocoTestReport:

  LINE    1847/2268   81.4%   (was 1519/2194, 69.2%)
  BRANCH   837/1390   60.2%   (was 53.2%)

against 417 JVM tests in 60 classes, all green.

The denominator moved too, 2194 -> 2268: the same push added production code of
its own, so this is not a pure numerator gain and the note now says so. The
Robolectric/isIncludeNoLocationClasses history is left exactly as it was -- it
explains why every pre-2026-08-24 figure was an artifact, and that is still the
most useful thing in the entry. "That date" is now spelled out, since the
headline date above it has moved and the phrase no longer points at itself.
