veyanet/veya-sdk ? reverse-engineered prompt

Build me the TypeScript SDK for VEYA, like a clean developer library people can install and use to talk to the VEYA network on Robinhood Chain.

I want it to handle local identity setup, hashing, signing, sealed execution, and sending proof or settlement requests in a safe, easy way. It should expose simple methods for creating keys, generating digests, proving input, sealing a decision, and anchoring commitments on chain when the right credentials are present. If something is missing, it should fail closed and return a clear result instead of guessing.

Please make it feel production ready, with strict TypeScript, good error handling, tests, and a few usage examples. Include readable docs so someone can understand how to initialize the client and call the main flows without digging through the source. If you need to check current docs or Node guidance online, go ahead and look it up.
