Add sorting to Workbench Market

[cinderzhan]

Summary

• Add a compact sort selector at the right of the Workbench Market search/category toolbar.
• Sort cards by GitHub Stars (high to low), displayed download count (high to low), source update time (newest first), or name (Chinese locale-aware A to Z). Missing values follow known values and equal values keep their prior order.
• Keep the current catalog order as the initial selection. Preserve the chosen sort when searching, changing categories, or switching Market/Favorites/Installed.

Update time data

Depends on awesome-dsh-workbench #27 to publish updatedAt in the market index. Until the updated index is deployed, entries without the field remain in their existing relative order for the update-time option. updatedAt is the latest default-branch commit time, not the daily metric scrape time.

Verification

• npm test (1544 passed)
• npm run typecheck
• npm run build
• node --check packages/dsh-desktop-workbenches/client.js
• git diff --check

The local checkout is on Harness 0.1.7-rc.2. This PR isolates the feature on main at 0.2.0-rc.2; packaged Windows UI verification remains for CI/QA.
