Subject: [PATCH] Pin backend main after merging fix/pg-boolean-columns

Why: Backend PR #62 merged as 3f438b9 (superseded by #64/#65); task card
requires re-pinning the gitlink to the backend merge commit before the
Dev PR can merge.
Evidence: backend go vet + go test ./... -count=1 all ok (29 packages);
merged tree content-identical to backend main.
Impact: modules/backend 685bd0d -> 3f438b9.
