Elrond 8a74f7beff ci: guard test-unit clauses and the rust-cache workspace root
Fail just test-unit when any combined-filter clause selects no tests, so a
renamed module or target cannot silently drop out of the union. Add a
cargo-metadata check that no dependency manifest sits under the workspace
root, run in Unit Tests before rust-cache can save, and select desktop jobs
for bin/hermit.hcl changes. Refresh comments that described removed flags.

// Fails when Swatinem/rust-cache would mistake dependencies for workspace
// members. rust-cache keeps target/ outputs only for packages whose
// manifest_path is outside the workspace root; a dependency whose manifest
// sits under the root (a registry under the checkout, a vendored source, a
// path dependency into a nested directory) is treated as workspace code and
// cleaned away. When that covers every dependency the root-workspace cache
// saves an empty target/, and the exact-key hit blocks every later save.
//
// Usage: cargo metadata --all-features --format-version 1 | node scripts/check-rust-cache-workspace-root.mjs
