Scaffolda tunn vertikal slice: pnpm-monorepo (shared/daemon/server/web)

- shared: typat WebSocket-protokoll (daemon/server/web som enda sanning)
- daemon: node-pty kör agenten (default gemini), strömmar pty över WS,
  auto-reconnect; fast pty-storlek
- server: WS-mux + token-auth + session-registry + headless-xterm scrollback
  (SerializeAddon) + routing av input till rätt session
- web: Vue 3 + Vite + xterm.js, session-lista, mobil-layout och
  fallback-tangentbord (piltangenter/Enter/Esc/Tab/Ctrl-C) som skickar
  escape-sekvenser rakt till pty:n -> styr sessionen även utan hooks
- workspace: pnpm-workspace.yaml (onlyBuiltDependencies: node-pty, esbuild),
  tsconfig.base, .npmrc (retry-inställningar), .env.example
