Vyper Vested Claims

Description: The contract doesn't provide any mechanism to transfer ownership, which could be problematic if the owner's private key is compromised or if ownership needs to be transferred to a different entity.
The contract sets the owner at deployment but lacks functionality to update it:

Impact: If the owner's private key is lost or compromised, there's no way to update the contract's administrative controls, potentially leaving the contract in a state where emergency functions like rescue_tokens cannot be called.

Recommended Mitigation: Implement a secure ownership transfer mechanism as described in the previous vulnerability.
