Migrate Verify workflow off archived actions-rs/toolchain

[Copilot]

GitHub Actions is deprecating Node.js 20 on runners in 2026, and actions-rs/toolchain@v1 is both archived and blocked from that transition. This PR removes the only structurally incompatible Rust setup action currently used in the repo’s workflows.

• Workflow migration

  • Replaced actions-rs/toolchain@v1 in verify.yml with actions-rust-lang/setup-rust-toolchain@v1
  • Kept the existing Rust setup unchanged in practice:
    • Rust 1.89.0
    • llvm-tools-preview

• Scope

  • Leaves the other workflow actions untouched
  • Addresses the archived Rust toolchain action called out as the immediate blocker for the Node 24 cutover

• Result

  • The Verify workflow no longer depends on the unmaintained actions-rs/toolchain action
  • Rust toolchain installation remains explicit and pinned

- name: Install Rust 1.89.0
  uses: actions-rust-lang/setup-rust-toolchain@v1
  with:
    toolchain: 1.89.0
    components: llvm-tools-preview
