Move the documentation to docs.varbase.vardot.com

Problem/Motivation

The documentation for this project now lives on the Varbase docs site: https://docs.varbase.vardot.com/developers/understanding-varbase/varbase-ai-recipes/varbase-ai-seo.

The repository still carries its own copy in the docs/ folder (one upstream status note), and the README repeats it. The two drift apart.

Steps to reproduce

1. Open README.md on the 1.0.x branch.
2. It does not link the docs page above.

Proposed resolution

• Remove the docs/ folder (one upstream status note).
• Keep README.md short: a Documentation link near the top, the install commands, and links to the docs page instead of the removed files.
• Add one line to AGENTS.md and CHANGELOG.md (Unreleased).
