Subject: [PATCH] fix(seo): use locale-prefixed URL for JSON-LD and twitter:url
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two SEO bugs in SeoGenerator emitted URLs without the active locale prefix.
Search engines indexing structured data on RU/HY pages would record the
wrong canonical, leading to either a hard 404 (when slugs differ between
locales — e.g. uxcore Russian transliterations) or silent locale-dilution
(when slugs are the same — e.g. /ru/articles/awareness-test).

Both issues stem from `router.asPath` returning the canonical (un-prefixed)
path under Next.js Pages Router i18n. The existing `originalUrl` already
prepends `localePath` correctly and is the source of truth used by the
`<link rel=canonical>` and `<meta og:url>` tags.

1. JSON-LD `"url"`: schema generator received `pageUrl` built from
   `domain + router.asPath`, dropping the `/ru` or `/hy` prefix. Now
   reuses `originalUrl` so JSON-LD matches canonical.

2. `<meta name="twitter:url">`: built from
   `https://keepsimple.io/${localePath}${alternateLink}` — a literal `/`
   between domain and `localePath` produced double-slash URLs
   (`https://keepsimple.io//ru/...` for RU, `https://keepsimple.io//...`
   for EN). Now also uses `originalUrl` for consistency and to
   eliminate the divergent-builder pattern that produced the original
   bug.

Verified on /ru/articles/awareness-test and
/ru/tools/longevity-protocol/about-project that JSON-LD `url` previously
emitted the unprefixed path; rendered HTML before fix attached in the
linkinator scan at reports/links-2026-04-28.json.
