Crate hsm_crypto_service 

Crypto business logic for the mini-HSM.

This crate sits between the low-level [atecc608b] driver and the USB protocol layer. It owns the slot conventions, the PIN session state, and the orchestration of the multi-step signing workflow (Nonce passthrough followed by Sign external).
