fix: remove poimen-root Application (external repo dependency)

- Removed dependency on external poimen.git repo
- Poimen manifests should be managed locally or via separate workflow
- Simplifies homelab GitOps to only manage homelab-owned services

-# Poimen project collection — manages poimen-memory, poimen-workflows, and poiman
-# Each repo tracks its own main branch (no prod branch). Poiman is the primary
-# orchestrator with k8s/argocd/ containing the AppProject and deployment structure.
-#
-# CI: All three repos trigger on main branch pushes (no image builds yet).
-# Future: Add build workflows for poiman once container runtime needs are clear.
