docs: fold k3s cluster setup + netcup-vps into infrastructure docs

Browse source 
Added to INFRASTRUCTURE.md:
- k3s cluster topology (cupfox control plane)
- Ollama inference serving (Neon-64GB, Caddy reverse proxy)
- netcup-vps ARM64 math stack (openblas, petsc, z3, julia)
- Reference to 4-Infrastructure/docs/k3s-cluster-setup.md

## k3s Cluster Setup
Detailed cluster setup documentation: `4-Infrastructure/docs/k3s-cluster-setup.md`
### Topology (cupfox control plane)
| Node | Tailscale IP | Role | Arch |
|------|-------------|------|------|
| cupfox | 100.110.163.82 | control-plane | amd64 |
| neon-64gb | 100.64.19.78 | worker (heavy) | arm64 |
| steamdeck | 100.85.244.73 | worker (gpu) | amd64 |
| racknerd | 100.80.39.40 | worker (edge) | amd64 |
### Ollama Inference Serving
- Host-level deployment on Neon-64GB (bypasses KServe RAM limits)
- Caddy reverse proxy on racknerd (:8443 → 100.64.19.78:11434)
- Troubleshooting: autosave.json stale config, passt port interception
### netcup-vps (ARM64 EPYC)
NixOS configuration: `4-Infrastructure/netcup-vps/configuration.nix`
ARM64-optimized packages:
- openblas, blis, lapack — multi-threaded linear algebra
- petsc, slepc — sparse/eigenvalue solvers
- flintqs, pari, gap, singular — number theory / algebra
- symengine — fast C++ symbolic (SymPy backend)
- fftw, suitesparse — FFT and sparse direct solvers
- z3, julia_11 — SMT and JIT numerics
k3s ports: 6443, 2379, 2380 (firewall updated)
