chore(ci): add github actions CI checks

[LNSD]

This pull request introduces a new continuous integration (CI) workflow for Rust projects. The workflow is defined in the .github/workflows/ci.yml file and includes jobs for building, testing, and formatting the code.

Key changes include:

• CI Workflow Setup:

  • Added a CI workflow triggered on pull requests and pushes to the main branch.
  • Configured environment variables for Rust, including CARGO_TERM_COLOR and RUST_BACKTRACE.

• Build and Test Jobs:

  • Defined a test job that runs on ubuntu-latest, checks out the repository, sets up the Rust toolchain, caches build files, and runs build and test commands (cargo check, cargo clippy, cargo test).
  • Included steps for running unit tests and documentation tests.

• Formatting Job:

  • Added a format job that also runs on ubuntu-latest, checks out the repository, sets up the Rust toolchain with rustfmt, and checks code formatting using cargo fmt.
