docs: rename project to Typoena

Project gets a proper name. Replaces "Ours" / "Our product" placeholders
in the QFD perception zone and the working title "typewriter" in
README/CONTEXT headers and the npm name. "Typewriter" the category
noun (the writing-machine concept) stays unchanged — Typoena is the
brand, typewriter is the category. SoftAP SSID typewriter-setup and the
repo directory are deliberately left as-is.
