Add podAffinity, podAntiAffinity and topologySpreadConstraints fields to DWOC config.workspace, applied to all pods created for DevWorkspaces: workspace pods, PVC cleanup jobs and backup jobs. Workspace restore is covered implicitly as it runs as an init container in the workspace pod. Node affinity computed by the operator (e.g. pinning backup/cleanup jobs to the node a ReadWriteOnce PVC is attached to) is merged with the configured pod affinity/anti-affinity instead of overriding it. The backup cronjob controller now resolves the configuration per workspace (supporting namespace-scoped DWOC) instead of using only the global operator config, and the HandleRegistryAuthSecret signature is simplified accordingly. Document the new configuration options in docs/dwo-configuration.md. Co-Authored-By: Claude Code <noreply@anthropic.com> Assisted-by: Claude Code Signed-off-by: Anatolii Bazko <abazko@redhat.com>

Do not use workspace-resolved AuthSecret for backup jobs.
A workspace owner with the standard namespace edit role can create a DevWorkspaceOperatorConfig in the workspace namespace and set controller.devfile.io/devworkspace-config to it. The backup path then accepts its BackupCronJob.Registry.AuthSecret, reads that-named Secret from the operator namespace, and copies it into the workspace namespace.
Use the global configuration for registry-secret selection while retaining the workspace-resolved configuration for other backup settings.

- registryAuthSecret, err := secrets.HandleRegistryAuthSecret(ctx, r.Client, workspace, config, r.Scheme, log)

Could we source the operator-namespace authSecret from GetGlobalConfig() in this shared helper? If I’m reading the flow correctly, namespace editors can create a DWOC that names an operator-namespace Secret, which then gets copied into their namespace. Restore appears to allow this already, and this PR extends it to periodic backups.

@rohanKanojia Yes. HandleRegistryAuthSecret is the better place to enforce this boundary. My caller-only suggestion would protect backups but leave restore exposed.
The helper currently uses the caller’s AuthSecret to select a Secret from the operator namespace. Both backup and restore pass workspace-resolved configuration.
Keep the workspace-namespace Secret lookup first. If that Secret is absent, select the operator-namespace Secret only from GetGlobalConfig():
// Import pkg/config as wkspConfig.
globalConfig := wkspConfig.GetGlobalConfig()
authSecretName := ""
if globalConfig != nil &&
globalConfig.Workspace != nil &&
globalConfig.Workspace.BackupCronJob != nil &&
globalConfig.Workspace.BackupCronJob.Registry != nil {
authSecretName = globalConfig.Workspace.BackupCronJob.Registry.AuthSecret
}Use this instead of the current authSecretName assignment. If the global AuthSecret is empty, continue without authentication. Do not fall back to the workspace-resolved AuthSecret.
Retain the workspace-resolved configuration for scheduling and other backup settings. This limits the change to the cross-namespace Secret selection.
Regression coverage should check that:
- A workspace DWOC cannot select an arbitrary operator-namespace Secret.
- The globally configured Secret remains available.
- An existing workspace-namespace Secret retains precedence.
The finding remains open until the shared-helper change is verified.

If we use global config instead of workspace config, then we won't be able to configure AuthSecret via DWOC in che namespace, right?
