-- 1.29.6 — dependency-hygiene patch. Refreshes Cargo.lock to pull -- semver-compatible upstream fixes, clearing the RustSec advisories in -- the transitive tree: crossbeam-epoch 0.9.18->0.9.20 (RUSTSEC-2026-0204, -- reached via rayon) and the postgres-client dev-dependencies -- (RUSTSEC-2026-0178/0179/0180, via pgrx-tests only — never in the shipped -- .so). No source change, no wire-format change (stays v7), no SQL surface -- change, no REINDEX, byte-identical build output (gemm/turbovec/pgrx pins -- unchanged). This migration is intentionally empty.
