data: add Hanzo AI startup credits offer

[filtede98]

Adds Hanzo AI (hanzo) with the Hanzo Startup Program credits offer sourced from https://hanzo.ai/startups

[auscaster]

Thanks for this contribution. We updated the record so every fact matches the vendor's current pages and it can pass admission:

• Added the homepage as a source; rewrote profile text to the current product.
• Offer title and credits text match the page (up to $150,000 in credits, tier-1 VC backing required).
• Consideration unknown to none; added access instructions (weekly review).

Admission re-runs automatically on this new commit.
