Filesystem independent Dependency Rules

Groups and dependency rules currently rely on filesystem paths, see here. So they have to be define like this:

groups:
   - name: apps
paths:
   - "apps/**"
   - "ui-shares/wasm/**"

I’d like to also support having those rules based on packages or component names. Here’s an example:

groups:
   - name: api-layer
packages:
   - tangleguard-rest-api
   - tangleguard-graphql-api
   - tangleguard-middlewear-api
