Missing provider validation during first initialization

[pnevyk]

First initialization:

$ openlock sandbox
openlock supports multiple container runtimes. Pick one to use.

Detected runtimes:
  - podman  (recommended — rootless default)
  - docker

This will be saved to your global config (~/.config/openlock/config.yaml).
Override per-invocation with OPENLOCK_RUNTIME=docker|podman.
Choice [podman]:
Saved default_runtime: podman
Select a provider:
  1. anthropic  (Anthropic (Claude))
  2. openrouter  (OpenRouter)
> 1

Later in the process of sandbox creation:

Created .openlock/. Review and commit before sharing.

When I was asked about the provider, I specified 1 expecting that it will choose anthropic. It probably expects the name (e.g., anthropic), but there should be a validation. From the prompt, it's not clear what the user should specify.
