pub_api_client 4.0.0

Breaking changes

• Added SearchOrder.trending for pub.dev's trend-score ordering. Consumers
  with an exhaustive switch over SearchOrder must add a trending case.

Added

• packageLikes — public like count of a package, no authentication required.
• publisherInfo — public publisher profile.
• packageVersionScore — score of a single package version.
• packageVersionOptions — retraction status of a single package version.
• topicNameCompletion — every topic mapped to its package count.
• SearchResults.message, set when pub.dev could not fully honor the query.
• PackageScoreCard.weeklyVersionDownloads, WeeklyVersionDownloads, and
  VersionRangeWeeklyDownloads for total and version-range download histories.
• Repository.fromMap and Repository.fromJson.
• Re-exported the pubspec_parse dependency types exposed through
  PubPackage.latestPubspec.

Fixed

• Search queries and tags now percent-encode reserved characters such as #
  and & instead of silently truncating the request.
• fetchGooglePackages no longer sends a malformed tools.dart.dev publisher
  tag and now includes labs.dart.dev.

Deprecated

• SearchOrder.popularity; use SearchOrder.downloads.
• PackageScore.popularityScore; use
  PackageScore.downloadCount30Days.
• LatestVersion; compare PubPackage.version directly. Removal is scheduled
  for 5.0.0.

Other changes

• Documented pub.dev's 10-page search limit and its effect on recursive search
  helpers.
• Modernized analysis, CI, and automated publishing. Releases now authenticate
  to pub.dev with GitHub OIDC instead of a long-lived workflow credential.
