Walkthrough

The pull request raises the Rust MSRV and pinned toolchain from 1.97.0 to 1.97.1, updates related documentation and Clippy settings, changes benchmark warning enforcement, and clarifies review configuration comments.

Changes

Rust toolchain alignment

Layer / File(s)	Summary
Rust version alignment Cargo.toml, rust-toolchain.toml, clippy.toml, AGENTS.md, CONTRIBUTING.md, README.md, docs/RELEASING.md	Rust version requirements, toolchain pins, Clippy settings, and documentation now use Rust 1.97.1.
Benchmark warning policy justfile	bench-compile uses CARGO_BUILD_WARNINGS=deny for both benchmark compilation commands.
Review configuration comments .coderabbit.yaml	Comments document the legacy commit-status requirement and explain why review-progress reporting remains disabled. Configuration values are unchanged.
