Description

Registry contract storing all DAO metadata and token addresses.

Tasks

• Create contracts/dao_registry/core.rs
• Define registry storage: HashMap<[u8;32], DAOEntry>
• Implement register_dao(token_addr, class, metadata_hash, treasury) -> DaoId
• Implement get_dao(token_addr) -> DAOMetadata
• Implement list_daos() -> Vec<DAOEntry>
• Implement update_metadata(dao_id, metadata_hash) - owner only
• Add event emission: DAORegistered, DAOUpdated
• Add WASM exports
• Create contracts/dao_registry/mod.rs
• Add unit tests (10+ test cases)

Acceptance Criteria

• DAOs can be registered with metadata
• Registry lookups work by token address
• Only DAO owner can update metadata
• Unit tests: registration, lookup, listing, updates
