fix(model): Adhere to omitExcluded for projects in getDependencies()

Previously, `getDependencies(omitExcluded = true)` only filtered excluded
packages from results but still traversed all projects. This caused
inconsistencies when dependency edges only exist in excluded projects (e.g.
test-only submodules).

Now excluded projects are also skipped during traversal, ensuring that
dependencies which are only reachable through excluded projects are not
discovered.
