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.
