#!/usr/bin/env bash
#
# ship.sh — End-to-end CLI release pipeline.
#
# Standalone backup for when GitHub Actions is unavailable (org shadow-ban,
# CI outage, etc). Mirrors what release.yml + docker job in CI would do.
#
# Pre-requisites:
#   - scripts/release.sh already ran → version.go bumped + tag created locally
#   - SENTRY_DSN exported (Sentry disabled in build if missing)
#   - docker logged in to docker.io as the org user
#   - SSH key for Hetzner publishing (see publish-cli-release.sh)
#
# Pipeline:
#   1. Sanity: clean tree, tag at HEAD, version.go matches
#   2. goreleaser build (skip GH publish — produces dist/*)
#   3. Rsync to Hetzner via web/scripts/publish-cli-release.sh
#   4. Multi-arch Docker build + push (amd64 + arm64) to Docker Hub
#   5. Smoke checks (torrentclaw.com/version + docker run image version)
#   6. Prune Forgejo releases older than FORGEJO_PRUNE_DAYS (default 90)
#   7. Optional `git push --follow-tags`
#
# Usage:
#   scripts/ship.sh                  Detect version from internal/cmd/version.go
#   scripts/ship.sh 0.9.12           Explicit version
#   scripts/ship.sh --dry-run        Preview steps, no side effects
#   scripts/ship.sh --push 0.9.12    Also git-push tag to GH afterwards
#
# Env knobs:
#   SENTRY_DSN              telemetry DSN injected at build time
#   RELEASE_SIGNING_PUBKEY  ed25519 pubkey (base64) for self-update signature check
#   DOCKER_IMAGE            default torrentclaw/unarr
#   PUBLISH_SCRIPT          default ../torrentclaw-web/scripts/publish-cli-release.sh
#   SKIP_DOCKER=1           skip Docker build/push
#   SKIP_HETZNER=1          skip Hetzner publish
#   SKIP_SMOKE=1            skip smoke checks
#   SKIP_FORGEJO_PRUNE=1    skip Forgejo retention prune
#   FORGEJO_TOKEN           PAT with write:repository for prune (no token = skip + warn)
#   FORGEJO_PRUNE_DAYS      retention window, default 90 days
#   FORGEJO_REPO            default torrentclaw/unarr
#
