Continue an OpenSpec change

Create one artifact — the next one whose dependencies are satisfied — and stop, so the user reviews each step before the next is generated.

Steps

1. Select the change. If not named or inferable from context, run openspec list --json and ask the user to pick from the most recently modified 3-4 changes, marking the most recent as "(Recommended)". Never guess.

2. Check status:

   openspec status --change "<name>" --json
