Briven/scripts/doltgres-version-check.sh

#!/usr/bin/env bash
# Doltgres version tracker — compares our PINNED doltgresql image against the
# latest upstream release, so we "move along" when DoltHub ships fixes.
#
# WHY: Doltgres is Beta; releases carry lock/concurrency/panic fixes we depend on
# (see docs/knowledge-base.md → "INCIDENT 2026-08-01" — 0.56.6 locked under load,
# fixed by upgrading to 0.57.2). This is a MANUAL, on-demand check — NOT a
# Watchtower/host-side poller (forbidden by infra/CLAUDE.md). Run it locally or
# from the brain cron; it never runs on the deploy host and never auto-upgrades.
#
# Usage:  bash scripts/doltgres-version-check.sh
# Exit:   0 = up to date, 10 = newer release available, 1 = error.
#
# On a newer release: follow the tested upgrade procedure in
# docs/knowledge-base.md → "Doltgres version pinning + upgrade process".
