Add reproducible build system, native Unraid plugin, and WebUI
- versions.env pins podman, conmon, crun, netavark, aardvark-dns, passt,
  and fuse-overlayfs to verified upstream source checksums; SlackBuild
  recipes, scripts/build-packages.sh, checksums.sh, release.sh, and
  update-versions.sh implement the reproducible pipeline; GitHub Actions
  workflows build in a Slackware container and publish releases without
  committing any binaries.

- plugin/podman.plg installs/updates/removes all eight packages (the
  seven components plus the plugin's own unraid-podman scaffolding
  package) via upgradepkg, using the official Unraid array-event hook
  mechanism (event/disks_mounted, event/stopping) instead of editing
  /boot/config/go. rc.podman and the sbin/ helper scripts implement
  storage creation, config seeding/sync, preflight checks, autostart
  with per-container Safe-Mode, and package verify/update/rollback.

- webui/plugins/podman implements the Dashboard, Containers, Pods,
  Images, Volumes, Networks, Logs, Terminal, Compose, and Settings
  panels against the approved mockup (webui/mockups/prototype.html),
  talking to podman system service exclusively via PodmanClient.php
  (libpod REST API over the Unix socket), with two documented
  exceptions: Terminal's one-shot exec model and Compose's use of the
  podman compose CLI, since libpod has no REST equivalent for either.

- docs/ARCHITECTURE.md and docs/ROADMAP.md record the design decisions
  and honest current status (syntax-checked, unit- and
  integration-tested against fake sockets/servers; not yet run against
  a real Unraid/Podman/Slackware system).

# webui/
Dynamix-style WebUI pages, following Unraid's plugin GUI convention of
`/usr/local/emhttp/plugins/<name>/`. `webui/plugins/podman/` is staged to
that path by the `unraid-podman` scaffolding package (see
`packages/unraid-podman/unraid-podman.SlackBuild`), which podman.plg installs
alongside the seven compiled components.
**Status: implemented**, covering all ten sections from
[docs/ARCHITECTURE.md, section 18](../docs/ARCHITECTURE.md#18-zukünftige-webui):
Dashboard, Containers, Pods, Images, Volumes, Networks, Logs, Terminal,
Compose, Settings. Not yet exercised against a real Unraid/Podman install —
see [docs/ROADMAP.md](../docs/ROADMAP.md) for what "implemented" does and
doesn't cover yet.
`webui/mockups/prototype.html` is the static, non-PHP clickable mockup this
implementation was built against — kept as the visual reference; it is not
staged into the package.

## Design constraints (see ARCHITECTURE.md for full rationale)
- Every panel talks to `podman system service` over its Unix socket via
`PodmanClient` — no `exec()`/`shell_exec()` of the `podman` binary
anywhere in `include/` or in the Containers/Pods/Images/Volumes/Networks/
Logs endpoints.
- **Two documented, deliberate exceptions**, not oversights:
- `ajax/exec.php` (Terminal) uses the real exec REST API, but as
one-command-in/output-out rather than a true interactive PTY — libpod's
interactive exec needs a persistent hijacked connection that doesn't
fit PHP-FPM's request lifecycle. See that file's header comment.
- `ajax/compose.php` (Compose) shells out to the `podman compose` CLI via
`proc_open()` with an argv array (never a shell string) — because no
REST endpoint for Compose exists in libpod at all. See that file's
header comment.
- The API socket is root-equivalent; no unauthenticated network exposure
beyond what Unraid's own WebUI auth already provides — see
[.github/SECURITY.md](../.github/SECURITY.md).
- Dark/light mode via CSS custom properties (`prefers-color-scheme` +
`[data-theme]` override), matching Unraid's own theme mechanism — no
separate theme toggle inside the plugin page.
