Subject: [PATCH] test(claude): wait for the child to record the frame, not
 just for its report

The scripted CLI writes its report at startup, so `until(readReport)` returned a
report with no user messages whenever the child had not yet read the line. The
assertion then failed under parallel load. Poll for the frame instead of for the
file.
