fix: explicit seo meta tags for social cards

[RYGRIT]

fixes: #832

https://cards-dev.x.com/validator prompt

WARN: The image URL https://npmx.dev/__og-image__/static/og.png specified by the 'twitter:image:src' metatag may be restricted by the site's robots.txt file, which will prevent Twitter from fetching it.

I will add Allow: /__og-image__/* to the robots.txt file. This method didn't fix the problem either; I need help.

📝 Walkthrough

Walkthrough

Adds Open Graph and Twitter metadata mappings to the home page SEO setup: useSeoMeta now accepts ogTitle, twitterTitle, ogDescription and twitterDescription in addition to existing title and description, and sets twitterCard to a large image summary. Separately, public/robots.txt is updated to add an Allow: /__og-image__/* rule before the final Disallow: / entry. No control flow or error-handling changes.

[danielroe]

this should probably be done on all pages, but we can merge this to test.

[RYGRIT]

Yes, that's what I was thinking too, and I'll continue to improve it. Since summary_large_image has remained unchanged, should we consider putting it into the nuxt.config.ts app configuration?

[RYGRIT]

It works very well!
