Pre/postdeploy command job: namespace mismatch (project.name vs project.namespace) and `undefined method 'include?' for false` crash

[Yuyz0112]

Summary

Two related defects in K8::Stateless::Command (used for pre/postdeploy commands):

1. Namespace mismatch. Command#namespace returns project.name, while the job template (resources/k8/stateless/command.yaml) and the rest of the deploy pipeline use project.namespace. When a project's namespace differs from its name (the project form allows this), delete_if_exists! / statuses query a namespace that may not exist, while the job itself is applied into project.namespace.

2. Crash instead of error. statuses rescues any kubectl error and returns false; done? then calls _statuses.include?(...), which raises:

Deployment failed: undefined method `include?' for false

masking the real error (in our case, the kubectl lookup failing because of defect 1).

Repro

1. Create a project where namespace != name and set a predeploy_command.
2. Deploy → deployment fails with the undefined method 'include?' for false message.

Suggested fix

• Command#namespace → project.namespace (consistent with the template).
• statuses rescue → return [] (and let the timeout surface) or re-raise a typed error so done? can report the underlying kubectl failure.

Happy to send a PR.
