Refresh README with Wired Grand Prize callout and product screenshots

[Copilot]

This update completes the README by adding the Wired Man vs. Machine Grand Prize mention, a terse product summary, and multiple product screenshots to make the experience scannable at a glance.

• README headline + summary
  • Add the Wired Grand Prize note at the top and a single-sentence description of Curator’s value.
• Screenshot gallery
  • Embed four product visuals with accessible alt text and SVG titles.

Curator is a tiny toolkit that captures GitHub diffs, scores every token for risk, and overlays a heatmap so reviewers immediately see what matters.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• update.code.visualstudio.com
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/hackathon-curator/hackathon-curator/curator/node_modules/.bin/vscode-test (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
