Develop the functionality to create a list of accounts eligible to claim assets

Create a functionality to specify the account list, assets, quantities, and expiration date for claiming.

This will enable airdrop distribution, secure asset allocation, and release capabilities.

No files, tests, or entry points are identified in the issue. Begin by locating the core account and asset-operation code, then clarify how account lists, assets, quantities, and expiration dates should be represented and validated. Done means a specified claiming workflow supports airdrops, secure allocation, and releases with tests.
