Subject: [PATCH] fix(test): update the three remaining KNOBS_HASH_VERSION pins
 to 14 (#3430)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Missed in the first pass because I ran a targeted set of test files instead of
the full suite. CI shards 3, 8 and 10 caught them:

  test/search/knobs-hash-reranker.test.ts:67
  test/cross-modal-phase1.test.ts:139,149
  test/search-alias-resolved-boost.test.ts:93

Each carries the running history of why the version moved, so each gets the
13→14 rationale appended rather than just the number swapped. No pins at 13
remain anywhere in test/.
