🤖 Platform infra modules

> 🤖 Written by an LLM (Claude), per factor X.

modules/ holds the reusable OpenTofu modules any CARLOS deployment builds on — see modules/README.md for docs and a self-hosting example.

The deployments Paul operates (flagship, Tito) instantiate these modules from the private repo carlosframework/platform-infrastructure, consuming them by git source URL — exactly the way a self-hoster's own infra repo would.
