Link or merge another Agentcard account that belongs to the same person. Use when the user says they already have an account under a DIFFERENT email or phone number — most often after identity verification (KYC) is rejected as a duplicate, which means that person already verified on another account. Two steps: (1) call with { type, identifier } to send a one-time code to that email/phone; (2) call again with the { ticket, code } to verify. If the identifier belongs to a different account, the two accounts are MERGED (the identity-verified account survives and gains the other's email/phone, so both sign in to one account); if no account has it, it is simply added to the current account.
