📝 Walkthrough

Summary by CodeRabbit

• Chores
  • Updated automated Rust checks to use the latest shared workflow configuration.
  • Standardised the development environment on the stable Rust toolchain.
  • Simplified toolchain configuration by removing the redundant version pin.

Walkthrough

The PR adds a stable Rust toolchain configuration for Mise, removes the .tool-versions Rust pin, and updates the pinned reusable Rust CI workflow commit.

Changes

Rust toolchain and CI

Layer / File(s)	Summary
Toolchain and CI configuration .mise.toml, .tool-versions, .github/workflows/rust-ci.yml	Mise now configures Rust as stable. The .tool-versions Rust pin is removed. The Rust CI job references a new pinned reusable workflow commit.

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

Merge Risk: 🟡 Moderate · up to e1388

The pull request currently points CI at an unavailable workflow revision, so required automation may not run as configured. Merge should wait until the reference is updated to a resolvable published commit.

Poem

A rabbit checks the Rusty trail
Stable tools are in the pail
CI hops to a newer pin
Old version files grow thin
Green builds greet the morning sun
