release(v2.0.2): rebrand README to Theta Directory, remove standalone-install framing (#185)

Removed "Why this over the alternatives"; fixed stale links to the old
per-repo GitHub Pages site to point at the unified theta-suite docs site;
made explicit this is deployed as part of Theta Suite, not standalone; added
the agent capability/install screenshots to the gallery.
