[question] 更改seo和seo规则：不使用www域名

[try to solve]

• Updated the repo SEO defaults to require apex (non-www) URLs for canonical, og:url, and sitemap entries.
• Switched the site generator defaults from https://www.onlinefreetools.org to https://onlinefreetools.org (including og-image.png).
• Updated the README live domain to the apex domain.
• Updated the static tool page public/tools/markdown-to-html.html so canonical, og:url, and og:image no longer use www.
• Removed legacy outputs that still contained www (public/en/ and public/dev-logs/index.html).
• Rebuilt the site and confirmed no www remains in canonical/og:url tags under public/**/*.html.
