fix(mcp): a close still offers books.verify; the test harness says why a server didn't start

GitHub's check on 794807ab: P8's fit-up replaced the step after
`books.close_period` (`books.verify`) with the audit and the
attestation, and P5's month_end_close eval, which follows only what
the books offer, lost the step it follows. The close now offers the
chain check first, then the audit the attestation rests on.

The portable macOS job failed every over-the-wire test with "the
server didn't say ready" and nothing else: the harness sent the
server's stderr to a file in the temp home and never showed it. It
now panics with that log, so the next run says what macOS refused.
