Adds append-only version history on disk (compose/{id}/v{N}/<files>) for
file-based (WorkflowID==0) Compose/Swarm stacks, with rollback to any past
version. Git stacks (versioned by commit) and Kubernetes are untouched.
Backend:
- Stack model: StackFileVersion, PreviousDeploymentInfo, Versions[]; new
StackFileVersionInfo type. APIVersion 2.43.0 -> 2.44.0.
- Versioned multi-file snapshot (entrypoint + AdditionalFiles) into v{N}/;
ProjectPath repointed via GetStackProjectPathByVersion each deploy. Retention
cap (20): Versions[] trimmed in-tx, old dirs deleted only AFTER the tx commits.
- Update handlers: RollbackTo (content read server-side from the target version,
never trusted from the client; validated 1..current & present in Versions).
- Create paths seed v1. stackFile reads ?version= (validated; negative -> 400).
- New GET /stacks/{id}/versions endpoint.
- Migration 2.44.0: move existing file-based stacks' files into v1/ (idempotent,
atomic pre-read of the full file set, skips git/kube/orphans).
Frontend:
- useStackVersions query + stackVersions key; StackEditorTab builds the full
history list; StackVersionSelector shows 'v{N} · date · author'; file/versions
caches invalidated (by prefix) after deploy/rollback.

F1: Stop routing git-backed stacks through a per-tick RedeployWhenChanged for
image-only updates. The git redeploy path short-circuits when the commit is
unchanged (so an upstream-digest update never applies) yet still git-fetches
every tick. Git stacks are now detect-only in the auto-apply path; their image
update lands on the next git change or via manual "Update now". File (non-git)
stacks still force-pull-redeploy immediately. The AutoUpdatePanel text no longer
promises daemon auto-update for git/externally-managed containers.
F2: Resolve registries for the file-stack redeploy the same way the established
userless/system path (RedeployWhenChanged) does, via the new
deployments.ResolveStackRegistries: scope to the stack author's endpoint access
and RefreshAndPersistECRTokens, instead of hand-passing Registry().ReadAll().
ECR-backed stacks now auto-update with fresh tokens.
F3: Add a 1m floor for the auto-update poll interval, enforced in the settings
Validate and mirrored in the frontend validation.
F4: Thread the application shutdownCtx into NewService and use it as the base
for the heal/update job operation contexts, so shutdown cancels in-flight work.
F5: Correct the updateEndpoint comment about monitor-only badge-cache warming
(only in-scope monitor-only containers are status-checked).
