chore(gbrain): bump migration to v1.35.0.0 after main merge

main shipped v1.34.0.0 (factory-export submodule) + v1.34.1.0 (update-check
hardening) while this branch was in flight. The migration file I named
v1.34.0.0.sh now belongs at v1.35.0.0 — the next minor on top of main,
matching the scale of split-engine work (new lib + orchestrator skip +
template overhaul + transcripts routing).

Renames the migration script and its test file; updates all internal
version references in both files. Behavior unchanged.
