Fix config generation error for zmq-enabled on upgrade

The field was moved to the top level but not marked nullable, so
upgrades from older configs (where it lived under advanced) failed
with "Field Is Not Nullable". The entrypoint already falls back to
true via yq's // operator.

 StartOS 0.3.5.1 wrapper for [Kamado Pool](https://github.com/Relaxo143/KamadoPool), a modern solo Bitcoin mining pool built on a patched fork of CKPool-solo with a Go middleware API and Svelte real-time dashboard.
 
-## Build
+## Prerequisites
+
+- **Docker** with [buildx](https://docs.docker.com/build/buildx/) plugin
+- **deno** — bundles the TypeScript embassy procedures
+- **yq** — parses `manifest.yaml` for package metadata
+- **start-sdk** — packs and verifies the `.s9pk` (from the [StartOS SDK](https://docs.start9.com/latest/developer-docs/specification/))
+- **KamadoPool source** — local sibling checkout at `../KamadoPool` (override with `KAMADO_SRC=/path/to/KamadoPool`)
+
+## Building
+
+### Universal package (x86_64 + aarch64)
+
+A universal `.s9pk` runs on any StartOS machine regardless of architecture. This is the default and what you should ship.
+
+**One-time setup** (re-run after each reboot):
+
+```sh
+make setup
+```
+
+This registers qemu binfmt handlers for cross-architecture emulation and creates a multiplatform Docker buildx builder. The arm64 build runs under emulation on x86 hosts, so it is significantly slower (~5-10x) than native.
+
+**Build:**
 
 ```sh
 make
 ```
 
-This runs `deno` to bundle the embassy TypeScript procedures, builds a multi-arch OCI image via `docker buildx`, and packs everything into `kamado-pool.s9pk` using `start-sdk`.
+This bundles the TypeScript procedures, builds Docker images for both architectures, and packs `kamado-pool.s9pk`. The universal package is roughly double the size of a single-arch package since it contains two Docker images.
 
-The build pulls KamadoPool source from a **local sibling checkout** (`../KamadoPool` by default) via a docker buildx named build context — no GitHub clone, no pinned SHA. If your checkout lives elsewhere, override it:
+### Single-arch (development)
+
+For faster iteration when you only need one architecture:
 
 ```sh
+make x86    # x86_64 only
+make arm    # aarch64 only
+```
+
+These skip the other architecture entirely — no emulation overhead.
+
+### Overrides
+
+```sh
+# Use a different KamadoPool source directory
 make KAMADO_SRC=/path/to/KamadoPool
+
+# Use a different buildx builder
+make BUILDER=my-builder
 ```
