## Context
Deploying new services required manually adding hostnames to
cloudflare_proxied_names/cloudflare_non_proxied_names in config.tfvars —
a separate file from the service stack. This was frequently forgotten,
leaving services unreachable externally.
## This change:
- Add `dns_type` parameter to `ingress_factory` and `reverse_proxy/factory`
modules. Setting `dns_type = "proxied"` or `"non-proxied"` auto-creates
the Cloudflare DNS record (CNAME to tunnel or A/AAAA to public IP).
- Simplify cloudflared tunnel from 100 per-hostname rules to wildcard
`*.viktorbarzin.me → Traefik`. Traefik still handles host-based routing.
- Add global Cloudflare provider via terragrunt.hcl (separate
cloudflare_provider.tf with Vault-sourced API key).
- Migrate 118 hostnames from centralized config.tfvars to per-service
dns_type. 17 hostnames remain centrally managed (Helm ingresses,
special cases).
- Update docs, AGENTS.md, CLAUDE.md, dns.md runbook.
```
BEFORE AFTER
config.tfvars (manual list) stacks/<svc>/main.tf
| module "ingress" {
v dns_type = "proxied"
stacks/cloudflared/ }
for_each = list |
cloudflare_record auto-creates
tunnel per-hostname cloudflare_record + annotation
```
## What is NOT in this change:
- Uptime Kuma monitor migration (still reads from config.tfvars)
- 17 remaining centrally-managed hostnames (Helm, special cases)
- Removal of allow_overwrite (keep until migration confirmed stable)
