fix(blog): strip query string and hash from SEO canonical and JSON-LD URLs

[aka-sacci-ccr]

Problem

The blog SEO sections (blog/sections/Seo/SeoBlogPost.tsx and blog/sections/Seo/SeoBlogPostListing.tsx) build the page URL used for the <link rel="canonical">, the url/mainEntityOfPage of the BlogPosting/Blog JSON-LD nodes, and the BreadcrumbList items. A request arriving with ?utm_source=x, ?page=2 or a #hash leaked those into every emitted URL, producing dirty canonicals and JSON-LD URLs that vary between requests for the same page.

This happened in both paths: with canonicalBaseUrl configured (withCanonicalBase preserved search + hash) and without it (the request URL passed through untouched).

Fix

Normalize in withCanonicalBase (blog/utils/jsonLD.ts), which every emitted URL flows through: keep only origin + pathname, dropping query string and hash in both paths.

Preserved behavior:

• relative canonicals are still resolved against req.url in the sections (no exceptions thrown);
• without a base, relative URLs still pass through unchanged (guarded by URL.canParse);
• the rest of the JSON-LD (readTime/aggregateRating guards, publisher, BreadcrumbList structure) is untouched.

Validation

• deno check, deno fmt --check and deno lint pass on the helper and both sections (pre-commit hook also ran the repo-wide check).
• deno eval assertions covering:
  • https://loja.com/blog/post?page=2#top → https://loja.com/blog/post (no base)
  • https://loja.com/blog/post?page=2#top + base https://www.loja.com.br → https://www.loja.com.br/blog/post
  • relative canonical /blog/dicas resolved against a req.url carrying ?utm_source=x, with and without base
  • relative URL without base passes through unchanged; clean absolute URLs are untouched

Summary by cubic

Strip query strings and hashes from blog SEO URLs so canonicals and JSON-LD stay clean and consistent across requests. Fixes noise from UTM params, pagination, and hash fragments.

• Bug Fixes
  • Normalize all SEO URLs via withCanonicalBase to origin + pathname; works with or without a base.
  • Applies to <link rel="canonical">, JSON-LD url/mainEntityOfPage, and BreadcrumbList; relative URLs without a base pass through unchanged.

Warning

Review limit reached

@aka-sacci-ccr, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 21 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

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.
