/**
 * Airdrop Service — check eligibility and generate claim calldata.
 *
 * Layered approach:
 * 1. Known airdrop contracts with hardcoded merkle root endpoints
 * 2. On-chain eligibility checks via direct contract calls
 * 3. PinchTab (browser tool) fallback for UI-based claims
 *
 * No single API covers all airdrops. This service maintains a registry
 * of known active/recent airdrops and their claim mechanisms.
 *
 * No external dependencies — uses viem for contract reads and
 * guardedFetch for any HTTP endpoints.
