feat: list top chargeback merchant groups

[0xSachinK]

Summary

• publish the exact shared-contract Top Chargeback Merchants group
• publish its staging counterpart
• document the one-time all-history, non-manual PayPal, Venmo, and Cash App threshold policy
• omit refresh cadence and tier metadata because this is a flat initialization cohort

Onchain verification

• staging group is indexed with 0 members, matching the calculated cohort
• shared group is indexed with 96 members
• all 96 desired wallets return true from direct registry membership reads
• curator, pending curator, resolver, visibility, and existence match the reviewed policy

Validation

• npm ci
• npm run check

Record the one-time evaluation timestamp

Once a maker crosses the threshold after initialization, the no-date-cutoff criterion says that wallet qualifies while the explicitly non-refreshed cohort will continue to exclude it. Record the snapshot/as-of timestamp for this one-time calculation, in both the production and staging metadata, so the published membership predicate remains accurate and reproducible.

State the threshold in USDC

The intended threshold is 10,000 USDC, but this describes it as $10,000, which denotes a USD amount rather than an exact token quantity. If USDC deviates from $1 or an evaluator reconstructs eligibility using token units, these are different predicates; identify the threshold as 10,000 USDC here and in the staging metadata.
