Adds WalletService over gRPC mirroring the existing REST surface 1:1: * GetAddress(GetWalletAddressRequest) → GetWalletAddressResponse * GetBalance(GetWalletBalanceRequest) → GetWalletBalanceResponse * Approve(WalletApproveRequest) → WalletApproveResponse Pure-gRPC consumers (e.g. Indelible's wallet-less external-signer flow that still wants /diagnostics + balance) no longer need to keep a REST client alongside just for wallet ops, and the dual-transport SDKs can stop returning UnsupportedOperationException on their *GrpcClient. Implementation notes: * New proto/antd/v1/wallet.proto added to build.rs's compile list and the grpc/mod.rs serve registration. * WalletServiceImpl in grpc/service.rs reuses antd/src/rest/wallet.rs's handler bodies — Client::wallet() access is transport-agnostic; the approve path spawns a tokio task to match REST. * Missing wallet returns Status::failed_precondition (the gRPC analog of REST's 503 service-unavailable for this case) with the same "wallet not configured — set AUTONOMI_WALLET_KEY" message. Out of scope: * SDK fan-out — covered in 11 follow-up PRs (rust/go/py/java/kotlin/ csharp/ruby/dart/swift/cpp/elixir). * Wallet configuration over gRPC — V2-335 (post-v1.0). * External-signer prepare/finalize — shipped separately via the UploadService + ChunkService PrepareChunk/FinalizeChunk RPCs from the V2-284 daemon PR. Gates on dev2: * cargo check / clippy -- -D warnings — clean on antd + antd-rust. * cargo test — 37/37 passing. * cargo fmt --check — clean.

Adds 3 new methods on GrpcClient mirroring the existing REST surface: * wallet_address() -> WalletAddress * wallet_balance() -> WalletBalance * wallet_approve() -> bool Implementation notes: * New WalletServiceClient field on GrpcClient, constructed in connect() alongside the existing health/data/chunks/files stubs. * build.rs adds antd/v1/wallet.proto to the tonic_build compile list. * A missing wallet on the daemon (no AUTONOMI_WALLET_KEY) maps to Status::failed_precondition; the client surfaces it as AntdError::Grpc with that code — same wrapper used by the other gRPC errors. Tests: * MockWalletService + start_wallet_mock_server helper that extends the existing start_mock_server pattern with the new service. * UnconfiguredWalletService for the failed-precondition path. * 4 new tests parallel to the REST wallet tests: address, balance, approve, plus the unconfigured-wallet error mapping. Gates on dev2: * cargo check / clippy --tests -- -D warnings — clean. * cargo test — 60/60 passing (56 existing + 4 new). * cargo fmt --check — clean. Depends on the antd-side daemon PR landing first. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
