bluebluesoda 49d34f3748 feat(images): optional Arch Linux rolling image builder

- scripts/90-arch-image.sh: builds vpsmgr/arch-sshd from images:archlinux/
  current; unlike other image scripts it always deletes and rebuilds (rolling),
  records Archlinux<YYMM> in the image description, keeps the image slim and
  deletes the base afterwards
- Register Arch Linux label + rolling-release blurb and a gray triangle icon
  in the user panel reinstall dialog
- Docs (README, architecture, development, AGENTS) and image tests updated

Development

Building

./build.sh [VERSION] compiles the Go binary into bin/vps. It requires any Go that supports toolchain auto-switch (≥ 1.21); src/go.mod pins the exact toolchain (go1.26.5).

./build.sh                 # current OS/arch
GOOS=linux GOARCH=arm64 ./build.sh   # cross-compile

Always CGO_ENABLED=0 (build.sh and the release workflow do this). The project is pure Go with no cgo; leaving cgo on pulls in Go's runtime/cgo bootstrap and a C toolchain whenever the standard net package is built, which fails on machines with a broken/absent gcc. Release binaries are therefore static and toolchain-free.

Testing

cd src
CGO_ENABLED=0 go vet ./...
CGO_ENABLED=0 go test ./...

The CI release workflow also runs vet+test with CGO_ENABLED=0 on amd64.

Developing against Incus

The panel talks to Incus over its Unix socket (/var/lib/incus/unix.socket, group incus-admin). For a local dev loop:

# add the Zabbly LTS repo and install Incus (Debian 12/13, Ubuntu 22.04+)
curl -fsSL https://pkgs.zabbly.com/key.asc -o /etc/apt/keyrings/zabbly.asc
echo 'deb [signed-by=/etc/apt/keyrings/zabbly.asc] https://pkgs.zabbly.com/incus/lts-7.0/ trixie main' > /etc/apt/sources.list.d/zabbly-incus.list
apt-get update && apt-get install -y incus
incus admin init --preseed < ...   # or use scripts/10-incus.sh
usermod -aG incus-admin "$USER"    # socket access without root

vps install does all of this on a real host; the exec API is exercised by internal/lx over websockets (no incus CLI needed at runtime).

Releasing

Tag a version (v*); the .github/workflows/release.yml builds amd64/arm64 with CGO_ENABLED=0, runs vet+test, attests build provenance (SLSA) and uploads a release with checksums. install.sh downloads the prebuilt binary from the latest release, falling back to a local build.

Conventions

Small, single-purpose commits — one commit per bug/feature.
Commit messages follow the existing style (short subject, then a bullet list of what and why).
Shell scripts: set -uo pipefail, helpers log/die/warn, bash -n checked, Python one-liners used only where the stdlib is enough.
The panel templates embed two languages (zh / en) via {{if eq .Lang "zh"}}...{{else}}...{{end}}.
