Description

### What would you like to be added?

Fine-Grained Kubernetes Resource Dependency Analysis

### Why is this needed?

Kusion initially used ordered kinds to determine the dependency order between Kubernetes resources. This [PR](https://github.com/KusionStack/kusion-module-framework/pull/41) changed the chain dependency model to a graph-based dependency model, but it still does not meet our requirements.

The issue is that dependency based on resource kinds cannot fully capture all scenarios. For example, a Deployment may use a ConfigMap, but an unreferenced ConfigMap might still be marked as a dependency of the Deployment, preventing the deletion of the isolated, unreferenced ConfigMap.

Therefore, we need a method that can analyze true resource-level dependencies directly from the spec, rather than relying on coarse-grained kind-based dependencies.

Research direction

No files, tests, or entry points are named. Start by reviewing the related issues and pull requests, then inspect the existing kind-based and graph-based dependency model. Done means the design and implementation can identify true resource-level dependencies from resource specs rather than coarse resource kinds.
