fix(ready): show correct message when all issues are closed (bd-r4n)

When bd ready found no ready work, it always showed 'all issues have
blocking dependencies' even when there were no open issues at all.

Now it checks if any open/in_progress issues exist:
- If no open issues: shows 'No open issues' (green)
- If open issues but all blocked: shows 'all issues have blocking
  dependencies' (yellow)
