feat: Remove herodo from monorepo and update dependencies

- Removed the `herodo` binary from the monorepo. This was
  done as part of the monorepo conversion process.
- Updated the `Cargo.toml` file to reflect the removal of
  `herodo` and adjust dependencies accordingly.
- Updated `src/lib.rs` and `src/rhai/mod.rs` to use the new
  `sal-vault` crate for vault functionality.  This improves
  the modularity and maintainability of the project.
