### Changed
* Smart-contract Wasm builds in this workspace now target `wasm32v1-none` instead of `wasm32-unknown-unknown`. `smart_contracts/contracts/.cargo/config.toml` sets `target = "wasm32v1-none"` and replaces the old `-C target-feature=-bulk-memory` rustflag with `-C link-arg=--import-undefined`; all other flags were dropped since `wasm32v1-none` enforces the Wasm MVP feature set on its own. The repo-root `rust-toolchain.toml` and `smart_contracts/rust-toolchain` were bumped accordingly, moving this workspace off its previously pinned dated nightly onto the `1.98.0` stable channel.

* `wasm32v1-none` and `-C link-arg=--import-undefined` require a Rust toolchain no older than `nightly-2025-08-03`. This workspace now builds with `1.98.0` stable, which postdates that requirement, but third-party contracts built against this crate's API on their own nightly toolchain must bump to at least `nightly-2025-08-03` (or a later toolchain) to keep building.
