Frontend: scroll fix, SSE reconnect, toast global, stale states, theming

Browse Source 
5 bloques en una pasada:

A. Scroll fixes (síntoma reportado por el usuario):
   - run-timeline: nuevo flag _userScrolledUp con detección por rAF en
     bindScroll. Auto-scroll al final SOLO si el usuario está abajo
     (umbral 150px) o si él mismo disparó un optimistic bubble. Cuando
     el usuario manda mensaje, se resetea el flag y se scrollea.
   - conversation-inspector: mismo patrón. ui:chatScroll respeta el
     flag userScrolledUp del emisor para no perseguir al usuario que
     lee arriba.
   - .bubble: + min-width:0, overflow-wrap:anywhere para URLs/JSON
     largos sin espacios.
   - <pre>: + overflow-x:auto, max-width:100%.
   - chat-simulator: textarea con resize:vertical, min/max heights
     viewport-friendly. inputs-col con overflow-y:auto.

B. Stale state options:
   - conversation-list y conversations-crud: dropdowns ahora muestran
     IDLE / CART / SHIPPING / AWAITING_HUMAN. Quitados BROWSING,
     BUILDING_ORDER, WAITING_ADDRESS, WAITING_PAYMENT, COMPLETED.
   - main.js: simulated plan.next_state pasa a CART.

C. SSE resilience (lib/sse.js):
   - connect() con backoff exponencial (1s → 30s).
   - safeParse() helper: cada evento envuelve JSON.parse en try-catch
     para que un payload malformado no rompa otros listeners.
   - reset retryDelay al primer "hello" exitoso.
   - ops-shell: indicador con dot (verde "En vivo" / naranja pulsante
     "Reconectando…") en lugar de texto plano.

D. Toast service global (public/lib/toast.js):
   - API simple: toast({ kind, text, ms }). Apila, animación slide-in,
     auto-dismiss 4s. Click para cerrar.
   - safeFetch en api.js: wrapper que dispara toast en network error y
     non-OK. Migrados simEvolution + retryLast.
   - chat-simulator usa toast en lugar de status text efímero.

E. Theming con CSS vars:
   - public/styles/theme.css con paleta completa (panels, borders,
     text, accents, bubbles, charts, radii, shadows). Linkeado desde
     index.html.
   - Migrados a var(--*) los 5 componentes más visibles:
     run-timeline, chat-simulator, conversation-inspector,
     conversation-list, home-dashboard. Custom properties heredan a
     través del shadow DOM, así que los demás componentes pueden
     migrar gradualmente sin cambios estructurales.
   - home-dashboard ya tenía vars locales: ahora apuntan a las globales.

Backend: 192/192 tests pasando. Sin cambios de API.
