test: ship triage asserts each failure's in-branch/pre-existing label (W7b ship triage)

The old check passed if the words 'in-branch', 'pre-existing', 'math' and
'string' appeared anywhere in the final message, in any pairing. The prompt
now asks for a closing JSON map; helpers/ship-triage-labels.ts reads it (or
unambiguous per-failure lines) and the test requires truncate/string ->
in-branch and divide/math -> pre-existing, plus a Bash call that ran the
suite. Stored outputs show swapped, words-only and one-label runs fail.
Drops the untyped recordE2E extras (typecheck baseline shrinks by one).
