Rust 1.98.1: full best-practices refresh #9
Description
Rust 1.98.1 is the current stable toolchain.
Do a complete repository refresh against Rust 1.98.0/1.98.1 rather than only replacing a toolchain version:
- Read the official Rust 1.98.0 and 1.98.1 announcements and detailed release notes/changelog.
- Review relevant language, standard-library, rustc, Cargo, Clippy, rustfmt, target/platform, and tooling changes.
- Review all Rust code,
Cargo.toml/Cargo.lock, CI, Docker/build tooling,SKILL.md, README/docs, examples, lints, and project conventions for newly preferable patterns or obsolete workarounds. - Adopt useful newly-stable features and current best practices where they improve the project; remove workarounds that current stable makes unnecessary.
- Keep the intentional MSRV contract separate unless there is a separately justified reason to raise it.
- Run the full CI-equivalent test matrix and fix fallout.
- If current stable is already fully reflected, document what was reviewed and close this issue as a no-op.
Generated as the initial queue item for the passive stable-Rust maintenance workflow.

No-op after full 1.98.0/1.98.1 review: this queue item was generated after the relevant modernization had already merged in #8 (merge commit d40832f).
Reviewed against the official Rust 1.98.0 release notes and the 1.98.1 point-release advisory. #8 already moved current development/CI/builds to patched 1.98.1 while preserving the Rust 1.94 MSRV, adopted resolver 3 for the virtual 2024-edition workspace, adopted Cargo-native
CARGO_BUILD_WARNINGS=deny, and changed the WASM current-stable lane fromcargo checkto a real link to cover the post-1.96 wasm-ld behavior.rust-toolchain.tomlis already pinned to 1.98.1.The newly stabilized 1.98 APIs (
NumBuffer/integerformat_into, algebraic floating-point methods,substr_range/subslice_range, UTF-16 endian constructors, atomic slice helpers, etc.) do not correspond to an existing workaround or dependency in this workspace that should be mechanically replaced. The 1.98.1 vtable miscompilation is addressed by the existing 1.98.1 pin. No additional repository change is justified for this release.
