revert(domain): stay on knowledgestack.github.io for now

app.knowledgestack.ai is already serving the product landing page on
DO + Route 53, and path-based proxying from there would need a CDN or
nginx change — not worth the risk to production for a docs site.

Rolling every canonical / OG / Twitter / Schema.org / sitemap / robots /
README / SEO-doc reference back to knowledgestack.github.io/ks-xlsx-parser.

Also cleared the CNAME claim on the org-site repo (knowledgestack.github.io)
so GitHub stops trying to provision a cert for app.knowledgestack.ai. The
org landing stays live at https://knowledgestack.github.io/ — still links
to this project as a nice cross-promo.

Re-visit when we have a dedicated docs subdomain (oss./docs./open.) or
CloudFront in front of the DO app.
