dig-wallet-backend 0.31.1

Canonical event-driven Chia wallet backend for the DIG Network. Exports two carefully-partitioned seams: an `engine` seam (imported by dig-node — the single running wallet instance: state, sync, unsigned-spend construction, event emission; identity-parameterized, never holds a private key) and a `client` seam (used by dig-app — the event subscriber, spend review/decode, the signing interface + identity provider that hold the key). Clean-room, chia-wallet-sdk-based. Replaces dig-l1-wallet.

//! The shared `types` layer — the wire contract both seams import (SPEC §2).
//!
//! Pure, I/O-free data: identities, values/records, the event taxonomy, spend objects, and
//! the catalogued error type. This layer is ALWAYS compiled (it is not feature-gated) and
//! deliberately contains NO secret material — no `SecretKey`, mnemonic, or seed ever appears
//! here (the key-isolation invariant, SPEC §1d).
//!
//! The event taxonomy + its `WalletId`/`Amount`/`AssetId` payload newtypes are NOT defined
//! here — they are re-exported from the canonical `dig-events-protocol` crate, the ONE
//! ecosystem definition the engine emits against and dig-app subscribes against (#1067, #1072).
