Say three where a third test joined, and stop the name claiming to be exact

#80 added SafPickerRoundTripTest's rotation case to @FailsOnEmulatorApi37, because a
real rotation aborts the framework on android-37.0. Three tests carry the marker now --
two in Media3EngineTest, one in SafPickerRoundTripTest -- and five statements still
described two.

Four were counts, and wrong:

  status_check.yml  "notAnnotation removes the two tests that do not pass"
  status_check.yml  "The two API 37 tests the gating row above excludes"
  CLAUDE.md         "the gating leg runs the other 55"          (59 - 3 = 56)
  CLAUDE.md         "do not read a green run as evidence those two tests pass"

The fifth was worse, because it was not a count. The advisory job's header justified its
name with an invariant:

  "It is named for WHAT IT RUNS, deliberately. Both tests drive a full H.264 -> H.265
   hardware transcode through Media3Engine"

The rotation case drives no transcode. So the comment did not merely miscount -- it
asserted a property of the job's contents that had stopped being true, and that property
was the entire argument for the name.

The name is unchanged, deliberately, and the header now says so instead of implying the
question never arose. This is not a required context, it is red on every PR by design, and
it is one people have learned to look for; renaming a check costs more than the imprecision
does. What replaced the invariant is the honest rule: THE MARKER IS THE DEFINITION, NOT THE
NAME -- this job holds the tests that cannot pass on the API 37 emulator image, whatever
their subject.

Two things stay as they were because they are still true. "the two Media3EngineTest cases
that pass here" is correct: that class has four tests and two carry the marker. And the
decoder theory is still a claim about the Media3 pair alone, so it now says so rather than
being read as covering a rotation failure it has nothing to do with.

Nothing about the job's behaviour changes: same name, same continue-on-error, same marker,
same selection on both rows. Verified: yaml parses, five jobs, matrix still 33/34/35/36/37.

The check to re-run when a test next joins or leaves the marker, which is the event that
broke this twice:

  grep -rn "@FailsOnEmulatorApi37" app/src/androidTest --include='*.kt' | grep -v import | grep -c FailsOn

It must equal the number every corrected comment states. It is 3.

Closes #81.
