Hindi translations (/hi/blog/$slug)

Files here are Hindi mirrors of the EN posts in src/content/blog/*.md.

• Slug must match the EN canonical slug (so hreflang alternates pair cleanly).
• Keep the same published_at as the EN source so freshness signals line up; bump updated_at when you re-edit.
• Set language: hi in the frontmatter (the loader also defaults this).
• The route auto-emits hreflang alternates (hi-IN, en-IN, x-default) and og:locale: hi_IN.
• /sitemap-hi.xml lists every file in this directory.
