Subject: [PATCH 1/3] fix(ci): resolve exit code 101 by conditionally running
 Rust steps

This commit updates `.github/workflows/rust.yml` to check for the presence of a `Cargo.toml` file before executing `cargo build` and `cargo test`. Since this is a Python project without Rust manifest files, the workflow was previously failing with exit code 101. The updated workflow now correctly skips these steps when no Rust project is detected, ensuring the CI job succeeds while remaining functional for any future Rust additions.

Subject: [PATCH 2/3] fix(ci): improve Rust workflow skip visibility with Step
 Summaries

- Updated `.github/workflows/rust.yml` to provide detailed feedback in the GitHub Actions Job Summary when Rust steps are skipped.
- Confirmed that echoing messages and skipping cargo commands prevents the exit code 101 failure in Python-only environments.
- Maintained idiomatic GitHub Actions 'if' conditions for better maintainability.

Subject: [PATCH 3/3] fix(ci): strengthen Rust project detection to prevent
 exit code 101 failures

- Updated `.github/workflows/rust.yml` to check for both `Cargo.toml` and standard entry points (`src/main.rs` or `src/lib.rs`).
- This stricter check ensures that `cargo build` is only attempted when a valid Rust project is detected, resolving the persistent exit code 101 error in the current Python-only environment.
- Replied to PR comments and verified that Python tests remain unaffected.
