Determine and Enforce Correct Minimum Rust Compiler Version in Build Pipeline

[lquerel]

A user reported that the project fails to compile with Rust compiler version 1.79.0. Currently, our Cargo.toml specifies version 1.76.0 as the minimum, which seems insufficient based on this feedback. We need to determine the actual minimum compiler version required to compile the project. More importantly, we need to identify the right way to test this, as this issue was not caught in our build pipeline.
