feat(deploy): verify each tenant /buildinfo matches published SHA after redeploy
Closes the gap that let issue #2395 ship: redeploy-fleet workflows reported ssm_status=Success based on SSM RPC return code alone, while EC2 tenants silently kept serving the previous :latest digest because docker compose up without an explicit pull is a no-op when the local tag already exists. Wire: - new buildinfo package exposes GitSHA, set at link time via -ldflags from the GIT_SHA build-arg (default "dev" so test runs without ldflags fail closed against an unset deploy) - router exposes GET /buildinfo returning {git_sha} — public, no auth, cheap enough to curl from CI for every tenant - both Dockerfiles thread GIT_SHA into the Go build - publish-workspace-server-image.yml passes GIT_SHA=github.sha for both images - redeploy-tenants-on-main.yml + redeploy-tenants-on-staging.yml curl each tenant's /buildinfo after the redeploy SSM RPC and fail the workflow on digest mismatch; staging treats both :latest and :staging-latest as moving tags; verification is skipped only when an operator pinned a specific tag via workflow_dispatch Tests: - TestGitSHA_DefaultDevSentinel pins the dev default - TestBuildInfoEndpoint_ReturnsGitSHA pins the wire shape that the workflow's jq lookup depends on Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
