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.
CONTEXT.md fixes the project's user-facing vocabulary (Tracked, Local,
Save, Publish) and the principles that fall out of those definitions
(the device is a writing tool, not a sync engine; it does no git work
the user did not explicitly request). README's file-scopes section and
repo-layout listing point at the new glossary so a first-time reader
lands on canonical definitions, and the ADR log carries an inbound link
so future ADRs can rely on the same terms.
