Subnano local client 0.3.16

New installations prefer subnano.ai. Existing validated account origins, credentials, grants, reservations and interrupted operations stay with their original host. Both strict release channels remain available.

Startup waits for concurrent account setup before auditing saved authority. A signer being persisted cannot be mistaken for an abandoned partial account. Interrupted or corrupt state still fails closed without replacing identity.

Native Nano signed domain and saved payment resources remain unchanged. An unresolved purchase on the other official host offers explicit continuation without moving credentials or replaying the operation. Browser sessions and installed clients remain separate by origin.
