Move CLAUDE.md's instrumented counts with the test that changes them

The suite goes 60 -> 61 and the gating leg 57 -> 58, because the new join-failure
test carries no @FailsOnEmulatorApi37 and so runs on every level including 37.

FAILS_ON_EMULATOR_API37_BASELINE stays at 3, checked rather than assumed:
e2e-report-shape.sh counts lines matching '^[[:space:]]*@FailsOnEmulatorApi37',
which is three annotations -- the fourth occurrence in the tree is the KDoc at
Media3EngineTest.kt:195 saying a test is deliberately NOT marked, and the anchor
excludes it. Nothing here adds a marker.

Carried by this PR rather than the docs one so the file never states a count main
does not have.
