Oier Bravo Urtasun 67d1f82e6a refactor!: unify into one compose, drop airgap/mirror/dnsmasq/avahi/blessingskin
Collapse the override-file matrix into a single docker-compose.yml holding the
whole stack: drasl, minecraft, mc-backup, caddy, nmsr, uptime-kuma. Bring-up is
now just `docker compose up -d --build`.

Removed features (dead-ends for this deployment):
- airgap / full asset mirror (mirror-airgap.sh, mirror-mods.sh, 20-mirror.caddy,
  caddy local-CA export, /ca.crt)
- dnsmasq + avahi/mDNS + dns-records.sh + mdns-host-setup.sh + ENABLE_MDNS;
  DNS is now handled outside this repo (HOST_LAN_IP dropped)
- Blessing Skin auth variant (compose + 00-core-blessingskin.caddy + BS_* env)
- host-nginx-static variant (docker-compose.nginx.yml, nginx/ulicraft.conf.tmpl)
- build-stack.sh and its run modes (online/airgap/core)

Production ingress is the only path now: host nginx terminates TLS (LE certs)
in front of caddy on a localhost-only port; caddy routes every vhost by Host
header. Launcher downloads move mirror/launcher -> launcher/.

Docs: README, deploy skill, and plan/ rewritten to match; obsolete plan docs
(dnsmasq, blessing-skin, assets-mirror, full-airgap-mirror, dns-and-run-modes)
deleted.

# Minecraft server — itzg NeoForge
## Summary
`itzg/minecraft-server:java21`, NeoForge 1.21.1, offline-mode + authlib-injector
pointing at drasl. Mods via `PACKWIZ_URL`. itzg installs MC + NeoForge +
libraries + server mods on first boot and re-syncs on restart; the stack assumes
the internet is present, so `TYPE=NEOFORGE` boots normally every time.
## Server config
```
TYPE=NEOFORGE, VERSION=1.21.1, NEOFORGE_VERSION=21.1.x
PACKWIZ_URL=http://pack.${BASE_DOMAIN}/pack.toml
```
First boot installs MC + NeoForge + libraries + server mods into the `mc_data`
volume. Subsequent boots re-sync the pack against `PACKWIZ_URL`.
## Auth / config
```
ONLINE_MODE=FALSE
ENFORCE_SECURE_PROFILE=FALSE # pairs with drasl SignPublicKeys=false
JVM_OPTS=-javaagent:/extras/authlib-injector.jar=http://auth.${BASE_DOMAIN}/authlib-injector
```
authlib URL uses the `auth` subdomain; resolves internally via the caddy alias.
(Server still needs the agent even though Fjord clients have it built in.)
Memory: `INIT_MEMORY 4G`, `MAX_MEMORY 10G`, `USE_AIKAR_FLAGS TRUE`.
RCON enabled for mc-backup.
## Tasks
- [ ] Compose: authlib URL `http://auth.${BASE_DOMAIN}/authlib-injector`
- [ ] Compose: `PACKWIZ_URL=http://pack.${BASE_DOMAIN}/pack.toml`
- [ ] Mount `./runtime` for authlib-injector.jar at `/extras`
- [ ] `depends_on`: drasl + caddy (pack served before server installs)
- [ ] Confirm `ENFORCE_SECURE_PROFILE=FALSE` ↔ drasl `SignPublicKeys=false`
- [ ] Verify a client joins with their drasl skin
