Oier Bravo Urtasun 27237bc7c1 feat(mods): replace packwiz with distribution-fed custom mod volume
Drop packwiz entirely. The server now loads a filtered mod subset from a
local ./server-mods volume instead of fetching a packwiz pack at boot.

New flow:
- tooling/classify-mods.py (tomllib only, no network) reads each jar's
  META-INF/neoforge.mods.toml and seeds mods-sides.json with a side
  (client|server|both; default both). Existing entries are preserved.
- mods-sides.json: committed, keyed by jar filename, hand-editable override
  surface. Initial seed: 65 both, 11 client, 0 server (76 jars).
- tooling/sync-server-mods.sh mirrors the both/server jars from
  $DISTRIBUTION_WEB_ROOT into ./server-mods/ (authoritative; prunes strays;
  halts on a missing jar). Replaces render-pack.sh.
- compose: minecraft mounts ./server-mods:/mods:ro with REMOVE_OLD_MODS=TRUE
  (itzg auto-syncs /mods -> /data/mods). Removed PACKWIZ_URL, the pack.
  extra_host (auth. kept for authlib), and depends_on caddy (drasl kept).

Both classify-mods.py and sync-server-mods.sh resolve their source dir as:
CLI arg / MODS_DIST_DIR env / $DISTRIBUTION_WEB_ROOT (in that order).

Removed: tooling/render-pack.sh + add-custom-mod.sh (packwiz tooling),
pack/ (packwiz source), custom/ (76 jars now sourced from the distribution),
the pack. caddy vhost + its mounts/alias, and the packwiz .gitignore block.

Client distribution is UNCHANGED: HeliosLauncher still installs the full
modset from distribution.json. Docs (CLAUDE.md, plan/04/05/14, runtime)
updated; plan/04-packwiz.md stubbed as superseded by plan/04-mods.md.

# Minecraft server — itzg NeoForge
## Summary
`itzg/minecraft-server:java21`, NeoForge 1.21.1, offline-mode + authlib-injector
pointing at drasl. Mods come from a local `./server-mods` volume (mounted at
`/mods`), NOT packwiz — see `04-mods.md`. itzg installs MC + NeoForge + libraries
on first boot and auto-syncs `/mods``/data/mods` every boot; the stack assumes
the internet is present (for the NeoForge installer), so `TYPE=NEOFORGE` boots
normally every time.
## Server config
```
TYPE=NEOFORGE, VERSION=1.21.1, NEOFORGE_VERSION=21.1.x
REMOVE_OLD_MODS=TRUE # ./server-mods is the authoritative mod set
volume ./server-mods:/mods:ro
```
`./server-mods` is populated by `tooling/sync-server-mods.sh` (the `both`/`server`
subset of `mods-sides.json`, copied from `$DISTRIBUTION_WEB_ROOT`). First boot
installs MC + NeoForge + libraries into the `mc_data` volume; every boot itzg
mirrors `/mods` into `/data/mods` and prunes removed ones (`REMOVE_OLD_MODS`).
## Auth / config
```
ONLINE_MODE=FALSE
ENFORCE_SECURE_PROFILE=FALSE # pairs with drasl SignPublicKeys=false
JVM_OPTS=-javaagent:/extras/authlib-injector.jar=http://auth.${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: mount `./server-mods:/mods:ro` + `REMOVE_OLD_MODS=TRUE`
- [ ] Run `tooling/sync-server-mods.sh` before bring-up (populates `./server-mods`)
- [ ] Mount `./runtime` for authlib-injector.jar at `/extras`
- [ ] `depends_on`: drasl (authlib must resolve at boot)
- [ ] Confirm `ENFORCE_SECURE_PROFILE=FALSE` ↔ drasl `SignPublicKeys=false`
- [ ] Verify a client joins with their drasl skin
