upgrade_registry package

Render returns a markdown overview of the most recent entries. Never panics.

The rendered page carries an explicit scope disclosure (round-4 audit). What this registry proves is narrow and easy to over-read: an entry's ADDRESS is self-registered and therefore verified, but its NAME is an arbitrary self-asserted label that is neither unique nor checked against anything. Two entries may carry the same name, and a name may impersonate a well-known project. A reader who keys on the bold name rather than the address is trusting something this realm does not attest. Stating that in the output is the only available mitigation: the entries are immutable, and name uniqueness is deliberately NOT enforced because first-come uniqueness on a permissionless immutable registry would let an attacker burn every valuable name permanently.
