docs: redesign README (animated hero + product demo)

[andresdjasso]

@waleedlatif1 — README redesign, targeted at staging as discussed. Clean diff (just README.md + 3 image assets).

What

A visual redesign of the top-level README so it reads like the product:

• Animated hero — one self-contained looping image: sim logo, the headline with the cycle-loader, a chat composer, and workflow + integrations peeking in.
• One combined demo GIF — Integrate / Ingest / Build / Monitor header over an animated product tour: start a chat to build an agent → connect integrations → add a knowledge base → build the workflow visually → deploy → monitor runs in the logs.
• All imagery is rendered from the real product UI (no mockups), full content width.

Notes

• GitHub strips CSS positioning from READMEs, so the hero is baked into a single image rather than an HTML overlay — it renders identically everywhere.
• Off-white (#F8F8F8) backgrounds; in dark mode these read as light cards (the single-asset trade-off — GIF can't be theme-aware without doubling assets).
• Diff is README-only: the previous README's assets on staging are untouched.

PR Summary

Low Risk
README and marketing asset references only; no application, API, or infrastructure code changes.

Overview
Redesigns the root README for a shorter, visual-first layout instead of the long feature walkthrough with separate GIFs and logo wordmark.

The top now uses updated neutral badge styling, a full-width readme-hero.gif hero, and a one-line product description. Multiple mid-page sections (chat, files, knowledge, tables, workflows) and their old static assets are removed in favor of a readme-tour.gif after the npx simstudio quickstart and a compact Capabilities bullet list.

Quickstart / self-hosting copy is tightened: cloud CTA badge simplified, NPM flags described inline instead of a table, and Docker Compose vs manual setup grouped under Self-hosting. The footer "Made with ❤️" text is replaced with readme-built-by-sim-team.png.
