fix(config): portable sha256 — Linux ships sha256sum, not shasum

Browse Source 
resolve-user-slug and endpoint hashing exited 127 on Amazon Linux (shasum
is a macOS/perl tool). New _sha256_hex helper prefers sha256sum and falls
back to shasum, matching gstack-verify-gate's existing pattern; both call
sites converted.
