This is a major release PR that lands roughly two years of CATs development: the architectural quantum refactor (InfraFunction / Structure / Process / Plant), IPFS ingress/egress, CAR (Content-Addressable Router) test infrastructure, and project handoff to DynamicalSystemsGroup.
Two sub-PRs are merged into this release:

1. Architectural quantum
Clear separation of InfraFunction, Structure (PaaS/IaC), Process (FaaS), and Plant (SaaS), with ingress/egress on the action plane.
2. IPFS data mesh
End-to-end IPFS ingress/egress via Docker nodes, host peering, and content-addressed BOM/CID handling.
3. Infrastructure as code
Terraform + Kind + Docker Compose under
data/input/structure/, with lifecycle and cleanup improvements.4. Test & repo hygiene
Pytest cleanup harness, removal of stale verification tests, stop tracking generated integration outputs.
5. Governance
Project URLs, maintainer attribution, and DSG contributor credits under the new org.
