feat: add Rust toolchain configuration and update CI workflow

[softmarshmallow]

• Introduced a new rust-toolchain.toml file specifying the Rust version 1.92.0 with a minimal profile.
• Updated the GitHub Actions workflow to use the specified Rust toolchain version for builds.

---

Note

Low Risk
CI/config-only change that pins the compiler version; main risk is unexpected build breakage if some crates rely on a different Rust version.

Overview
Pins the project’s Rust toolchain to 1.92.0 by adding rust-toolchain.toml (minimal profile), making local and CI builds use a consistent compiler version.

Updates the build-canvas GitHub Actions workflow to explicitly install Rust 1.92.0 via dtolnay/rust-toolchain, reducing CI drift from stable.

Rust toolchain version inconsistency between CI workflows

Medium Severity

The PR adds rust-toolchain.toml pinning to Rust 1.92.0 and updates build-canvas.yml to use this version, but test-crates.yml still uses dtolnay/rust-toolchain@stable without specifying the version. This means tests run on the latest stable (currently 1.93.0) while builds use 1.92.0, and local development uses 1.92.0 from the toolchain file. This inconsistency could cause tests to pass in CI but fail locally, or introduce subtle behavioral differences between workflows.
