docs(us2): Soft Serve → Gitea 迁移事实与参考镜像 (Plane VPS-94)

- hosts/us2: Gitea 1.27.3-rootless 部署实况 (repo.windy.me SSH:2222/Web), 16 仓迁移核对, 备份/回滚; soft-serve 停用保留作回滚
- compose/gitea: 参考镜像 (rootless compose + 备份 sidecar + 一次性迁移脚本留档)
- AGENTS/inventory/compose README: 服务表与索引同步

-- No host ports published: Traefik TCP entrypoint `ssh` (`:2222` → `soft-serve:23231`, `HostSNI(*)`, `tls=false`) on `vw-net`. Container listens 23231 SSH / 23232 HTTP (git smart-http, no web UI) / 9418 git / 23233 stats (localhost only)
-- **镜像已固定** `charmcli/soft-serve:v0.12.2`(digest `sha256:554cc770…`, Docker Hub 稳定源; GHCR 为 dev/nightly 源且无 v0.12.x tag); `/soft-serve` 由 named volume `soft-serve_soft-serve-app` 承载, 旧匿名卷已清理(2026-08-30)
-- **非 root 运行**(2026-08-30, [W1N-248](https://linear.app/w1ndy/issue/W1N-248)): compose `user: "1000:1000"`(uid=windy, 镜像无内置用户); data 全量 `chown 1000:1000`, 容器内 `id` = uid 1000, 功能验证通过

 **Disk cleanup 2026-09-18** ([Plane vps VPS-93](https://plane.chans.xyz)): root 71% → **23%** (~33G freed) keeping soft-serve / vaultwarden / traefik (nghttpx kept running per operator choice). Removed: unused Docker images + orphan volumes (incl. `zitadel_data` 801M), dormant `/opt` dirs (dendrite + its disabled `dendrite.service` unit, mastodon, dailysync, keycloak, media-repo, authelia, conduit, npm, manager, fusion, zitadel, rustdesk), rootless podman storage (6.4G stale goauthentik), home dev caches, apt cache, journal 3.8G→162M (+`SystemMaxUse=200M` drop-in, active next boot), truncated container logs (nghttpx 550M / traefik / squid). Follow-up: nghttpx-proxy logs grow ~25M/day (INFO per-connection); root-cause log-level/rotation fix still open (needs container restart approval).
 
-Remaining running services on this host: `soft-serve`, `vaultwarden` stack, `traefik`, `nghttpx-proxy` + `squid-backend` (undocumented forward proxy, `/opt/nghttpx`). `/home/windy/authelia` (76M) left in place — outside approved cleanup scope.
