Commit Message

Add Applier for upgrading workloads in place (#5410)

Detecting an available upgrade is only useful if users can apply it
while keeping their configuration. Add the apply path that the CLI and
API will drive.

Add upgrade.Applier: it reloads the workload's saved config, re-runs the
check on fresh state (so a stale result can never drive an apply),
resolves the candidate from the registry, and rebuilds the run config
preserving the full user configuration — auth, authz, audit, telemetry,
tools filters, volumes, secrets, ports, permission profile, and more —
changing only the image, merged env/secrets, and re-resolved registry
URLs. New required env vars surface through the injected validator.

Crucially, the candidate image is verified and pulled (and the policy
gate runs) before the destructive stop/delete/start, so a missing or
unverifiable image leaves the running workload untouched — there is no
rollback once UpdateWorkload begins. Verification uses the same path as
thv run.
