syncProjectToMemfs rethrew the first rejected fetchBytes whatever file it
was, so one missing/unreadable sibling (a .kicad_sch body gone, a Q-1
phantom row, a transient 5xx) took the whole board open down behind
"download failed (404)". Now only the TARGET's failure rejects; siblings
are logged, counted and reported through onStatus, and KiCad reports a
missing sheet itself. kicad-runner.test.ts pinned the old contract with a
non-target file — corrected to a target; new kicad-runner.findings-q.test
gates both branches.
