build!: adopt GroveDB bincode across the workspace

[QuantumExplorer]

Issue being fixed or feature implemented

GroveDB #938 introduces the grovedb-bincode fork. Platform is adopting it in Platform #4625, but its Encode/Decode traits are distinct from crates.io bincode's traits. Moving rust-dashcore to the same fork lets Core, wallet, GroveDB, and Platform types share those traits directly, without a compatibility package or downstream Cargo patch.

What was done?

• Pin workspace dependencies bincode and bincode_derive to grovedb-bincode / grovedb-bincode-derive 2.1.0 from crates.io.
• Use those dependencies in dashcore, dash-network, hashes, key-wallet, key-wallet-manager, and RPC JSON, preserving existing feature names, optional dependencies, and Serde features.
• Document the Rust compatibility change in the changelog. Existing codec implementations, C/Swift interfaces, and build scripts are unchanged. This dependency migration does not automatically opt types into DecodeUntrusted or change ordinary decoding behavior.

How Has This Been Tested?

Passed locally on macOS. Workspace compilation, unit tests, and strict Clippy were rerun with the published 2.1.0 packages; their Rust source matches the previously tested fork revision:

• cargo check --workspace --all-targets --all-features
• cargo clippy --workspace --all-targets --all-features -- -D warnings
• cargo fmt --all --check
• cargo test --workspace --lib --all-features: 2,332 passed, 41 ignored.
• cargo test -p dash-network -p dashcore_hashes -p dashcore -p key-wallet -p key-wallet-manager -p dashcore-rpc-json --all-features, including existing wallet serialization integration tests and documentation tests.

The dependency graph resolves only the fork's bincode runtime and derives. Live-node integration and device builds were not run locally; native FFI targets are covered by workspace compilation and unit tests.

Breaking Changes

Rust consumers serializing these types must use the published grovedb-bincode 2.1.0 crate for compatible Encode/Decode traits. Existing serialized bytes and the C ABI are unchanged.

📝 Walkthrough

Walkthrough

The workspace now uses grovedb-bincode 2.1.0 and its derive package from crates.io. Package manifests inherit these dependencies, and the changelog documents the Rust trait compatibility requirements.

Changes

Bincode workspace migration

Layer / File(s)	Summary
Workspace dependency source Cargo.toml	The workspace defines bincode and bincode_derive as the grovedb-bincode packages at exact version 2.1.0.
Package dependency adoption and release notes dash-network/Cargo.toml, dash/Cargo.toml, hashes/Cargo.toml, key-wallet-manager/Cargo.toml, key-wallet/Cargo.toml, rpc-json/Cargo.toml, CHANGELOG.md	Package manifests inherit the workspace dependencies while preserving optional and serde settings. The changelog documents the updated fork traits, encodings, C interfaces, and Rust compatibility requirements.

Priority: ⬇️ Low — Defer the workspace bincode dependency migration because it preserves existing encodings and interfaces without a stated customer or production impact.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 5983e

This updates workspace serialization dependencies to published GroveDB bincode 2.1.0 crates while preserving package feature configuration. No merge-blocking production or compatibility risk is currently identified.
