Feature: proof-of-uniqueness leaderboard-safe attestation for airdrops/quotas

[Psalmuel01]

Building on per-app nullifiers, provide a ready-made pattern for airdrop/quota contracts: a verified-human-once claim a distributing contract can consume.

Scope

• A small reference contract + SDK helper that lets a distribution contract check "this human has not already claimed in this campaign" using the nullifier mechanism.
• Include a worked example (a demo airdrop) in the apps gallery.
• Document the anti-Sybil guarantees and limits.

Value

Turns the nullifier primitive into a plug-and-play anti-Sybil distribution pattern.

Acceptance

• A reference distribution flow enforces one-claim-per-human per campaign; demoed in the apps gallery; documented.
