feat(antd-rust): gRPC external-signer prepare/finalize parity with REST#169

Conversation
Adds 7 new methods on `GrpcClient` mirroring the existing REST client surface: * `prepare_upload(path, visibility)` / `prepare_upload_public(path)` * `prepare_data_upload(data, visibility)` * `finalize_upload(upload_id, tx_hashes)` (wave-batch) * `finalize_merkle_upload(upload_id, winner_pool_hash, store_data_map)` * `prepare_chunk_upload(data)` / `finalize_chunk_upload(upload_id, tx_hashes)` All call into the new `UploadService` and the extended `ChunkService` RPCs added on the daemon side. Consumers can now swap a REST `Client` for a `GrpcClient` without code change in the external-signer flow. Proto/build: * `build.rs` picks up `antd/v1/upload.proto`. * `grpc_client.rs` adds the `upload: UploadServiceClient<Channel>` field and constructs it in `connect()`. * Conversion helpers `prepare_response_to_result` / `finalize_response_to_result` / `payment_entry_to_info` map proto3 scalar-default fields back to the REST-style `Option<_>` shape on `PrepareUploadResult` (depth / pool_commitments / merkle_payment_timestamp populated only when `payment_type == "merkle"`). Tests (`grpc_tests.rs`): * Extends `MockChunkService` with `prepare_chunk` (new chunk + already-stored short-circuit) and `finalize_chunk` (echo upload_id). * New `MockUploadService` covers wave-batch, merkle, public/private visibility round-trip via upload_id encoding, and store_data_map true/false. * 12 new `#[tokio::test]` cases covering: - prepare_upload visibility forwarded / omitted - prepare_upload_public convenience wrapper - prepare_data_upload wave-batch / merkle - finalize_upload data_map_address present / absent - finalize_merkle_upload store_data_map true / false - prepare_chunk_upload new / already-stored - finalize_chunk_upload body forwarding 68/68 tests pass on dev2. Depends on the antd-side PR (UploadService + chunks prepare/finalize) to land first so the protos compile against `../antd/proto`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Closes the gRPC parity gap with REST: external-signer (UploadService + chunks PrepareChunk/FinalizeChunk) and WalletService are now reachable over gRPC, plus stream-download stubs return honest UNIMPLEMENTED/501 instead of pretending. All 11 gRPC-capable SDKs follow with matching fan-out. ## Additive (antd daemon) - gRPC UploadService + chunks prepare/finalize — external-signer two-phase upload + single-chunk publish over gRPC, mirroring REST 1:1 (#140) - gRPC WalletService — GetAddress / GetBalance / Approve, parity with REST /v1/wallet/* (#154) - /v1/data/prepare now honors visibility for public DataMap chunk bundling via data_prepare_upload_with_visibility (#138) ## Fixes (antd daemon) - Stream-download stubs (DataServiceStub.StreamDownload, REST /v1/data/stream/*) now return UNIMPLEMENTED / 501 honestly rather than empty success (#155) ## SDK fan-out — external-signer (gRPC prepare/finalize) All 11 gRPC-capable SDKs replace their stub raises with real gRPC calls to the new UploadService + ChunkService PrepareChunk/FinalizeChunk RPCs: - antd-rust (#169), antd-go (#170), antd-py (#171), antd-java (#172), antd-kotlin (#173), antd-csharp (#174), antd-ruby (#175), antd-dart (#176), antd-swift (#177), antd-cpp (#178), antd-elixir (#179) ## SDK fan-out — WalletService Same 11 SDKs gain walletAddress / walletBalance / walletApprove over gRPC: - antd-rust (#180), antd-go (#181), antd-py (#182), antd-java (#183), antd-kotlin (#184), antd-csharp (#185), antd-ruby (#186), antd-dart (#187), antd-swift (#188), antd-cpp (#189), antd-elixir (#190) ## SDK examples + build fixes - antd-ruby: payForQuotes tuple args as Hash for eth-0.5.13 compatibility (#131) - antd-go + ant-dev: add 03-chunks + 06-private-data examples; renumber 03-files to 04-files (#132) - antd-java + antd-cpp: close async client surface gaps (#133) - ant-dev: pull antd[rest,grpc] extras so 08_grpc example runs out of the box (#134) - antd-js + antd-py + antd-go READMEs: surface external-signer methods + 07 example (#135) - antd-elixir: 07_external_signer example via cast shell-out (#136) - antd-swift: 07_external_signer example + fix FinalizeUploadDTO optional address (#137) - antd-php: empty tx_hashes serializes as JSON object on finalize (#139) ## FFI - ant-ffi refresh against current ant-core API + Swift xcframework build pipeline (#150) - Android AAR build pipeline (#156) ## Infra - CI: auto-tag Go submodules on umbrella release tag push (#129) - Deploy: publish multi-arch withautonomi/antd image from ant-sdk release (#130) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
