feat(explorer) : sync sort column to URL query string

[ayushi-wq]

What changed

Sync the explorer's sort column to the URL query string (?sort=verified), matching the existing ?cat= category behavior. Filter/sort state now survives a page reload and is shareable via URL.

Source

N/A — this is a code change to site/explorer.js, not a dataset update

Checklist

• I edited data/providers.json and nothing else.
• I ran npm test and the dataset validation passed.
• For a verified change, I set verified: true with a last_verified date (today) and a real docs_url.
• For anything I couldn't confirm against the provider's own docs, I left it verified: false and explained what's unconfirmed.

Summary by CodeRabbit

• New Features

  • Sort selections are now preserved in the URL, allowing the selected table sort to be restored when reopening or sharing a page.
  • Valid sort parameters automatically apply the selected column and ascending direction.

• Bug Fixes

  • Updated the freshness badge to accurately report the oldest verified item as 14 days old.

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The explorer now persists and restores the selected sort column through the URL. The freshness badge now reports the oldest verified item as 14 days.

Changes

Explorer sort persistence

Layer / File(s)	Summary
Sort URL state site/explorer.js	syncURL writes non-default sort columns to the sort query parameter. applyURL validates the parameter, restores sortKey, and marks the matching header as ascending.

Freshness badge

Layer / File(s)	Summary
Freshness badge message badge-freshness.json	The badge reports oldest 14d instead of oldest 13d.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 7532c

The change is localized to restoring sort state from the URL; an ascending sort restored after reload may have inconsistent header styling, but no actionable merge-blocking risk remains.
