Repository dependency audit: Identify Rust crates usage across repositories

Description

We need to perform a dependency audit across all repositories to determine which ones use Rust and document the specific crates they depend on.

This task includes:

1. Iterating through all repositories in the S-Core organization.
2. Identifying which repositories contain Rust projects (presence of Cargo.toml).
3. Extracting the list of crates used from Cargo.toml and/or Cargo.lock.
4. Creating a consolidated report with the following information:
   • Repository name
   • Path to Rust project(s) (if multiple)
   • List of crates in use (with versions if available)

This is particularly important for the new source-of-truth repo introduced by Mark, but should be applied to all Rust-based repositories.

The report should be stored centrally.
