feat(swarm): add swarm self-improvement loop infrastructure

Adds complete k8s manifests, ArgoCD app, and Terraform namespace
resources for the Neuron swarm self-improvement loop system.

Each variant (alpha, beta, gamma) gets its own isolated namespace,
PVC, MCP/REST deployments, ExternalSecrets from Vault, RBAC for CI,
and a SQLite clone Job template for session startup.
