Code Review

This pull request clearly and effectively adds the rel attribute to the list of sorted attributes for the attr-sorted rule. The changes are well-implemented in the source code, and the accompanying tests provide good coverage for the new functionality, especially the interaction between rel and href.

Well done on:

• Correctly updating the sortOrder array in src/core/rules/attr-sorted.ts.
• Adding specific and relevant test cases in test/rules/attr-sorted.spec.js to verify the new behavior.
• Ensuring the generated distribution files (dist/) are updated accordingly.

The placement of rel (after type and before href) in the sort order seems logical and aligns with common usage patterns, for example, in <link> tags.

One minor suggestion for follow-up:

• Please ensure the documentation for the attr-sorted rule (likely in website/src/content/docs/rules/attr-sorted.md) is updated to include rel in the specified attribute order. This will help users understand the new correct ordering.

Overall, this is a solid and straightforward enhancement.

Summary of Findings

• Code Quality and Correctness: The changes are correctly implemented, and the logic for sorting attributes remains sound with the addition of rel.
• Testing: New test cases effectively validate the behavior of the rel attribute in relation to href.
• Documentation (Out of Scope of Diff): A recommendation was made to update the rule's documentation to reflect the new sort order including the rel attribute.

Merge Readiness

The pull request is in good shape and the changes are well-implemented. I recommend merging these changes after considering the documentation update for the attr-sorted rule.
