+> This branch includes:
+> - Hardening (replaced atoi() with strtol(), vendor.sh SHA validation, pinned GHA versions, OIDC releases)
+> - Update to the latest SQLite release (should be no-op, and backward compatible)
+> - Node.js release added Alpine/MUSL x64/arm64 and Windows arm64 prebuilds
+> - Node.js package now includes all prebuilds (so post-install scriptes!)
