Cowork mode blocked — "Missing HCS services: HNS, vmcompute" on Pro plan

Description

When starting a new chat and trying to select "Cowork" instead of "Chat", the Cowork toggle is disabled. Hovering over it shows the tooltip:

Missing HCS services: HNS, vmcompute

I am on the Pro plan, which I believe should include access to Cowork. The message appears to be an internal infrastructure/service-check error being surfaced directly in the user-facing tooltip instead of a clear message.

Steps to reproduce

1. Start a new chat on claude.ai
2. Look at the Chat / Cowork toggle
3. Try to select "Cowork"
4. Hover over the disabled toggle to see the tooltip

Expected behavior

Either Cowork works normally on the Pro plan, or a clear, user-friendly message explains why it's unavailable (e.g., plan limitation, regional rollout, etc.) instead of an internal service name.
