Add automated on-chain verification of supply-chain sustainability claims to close the greenwashing gap. Introduces SustainabilityRecord (carbon footprint, water usage, renewable energy %, waste recycling %, labor compliance doc hash) and SustainabilityStatus (Pending / Verified / Rejected) in types.rs, seven new errors in the 70–80 range in error.rs, and a SustainabilityContract with four public functions: record_sustainability, verify_sustainability, reject_sustainability, and get_sustainability. Records are keyed per-product on-chain; verified records are immutable and anchored with a certificate hash. Six unit tests cover the happy path, admin verification/rejection, invalid data, and overwrite protection.
Closes #173
