* Read the merge queue's notes in one git process so land and ready stay fast (GST-2198)
Rebuilding local queue state from refs/notes/gstack-trains ran one git cat-file per note: 14 to 15 s per land and first ready on the live 1,442 notes, growing about 8 s a week toward the 120 s command timeout. One git cat-file --batch now reads them all (about 120 ms on the same notes) and restores byte-identical records.

* Refuse a failed batched notes read instead of treating it as an empty queue (GST-2198)
When the one git cat-file --batch process fails, times out or overruns its buffer, rebuildFromNotes now returns fetched:false, so land --repair and the freeze lock refuse instead of reading no notes. The test's counting git shim now execs the git in git --exec-path, so a PATH git wrapper cannot loop back into it.
