Default still builds linux/arm64/v8+linux/amd64 for shipping,
but 'make PLATFORMS=linux/amd64' skips the arm64 leg on hosts
without qemu-user-static registered.
Replaces the git-clone-at-SHA source stage with a 'FROM scratch
AS source' stage that COPYs from a named build context. The
Makefile passes '--build-context kamado=../KamadoPool' by
default; override with 'make KAMADO_SRC=/elsewhere'. No more
SHA placeholder, no GitHub dependency, no re-clone on every
build — and the image always reflects the working tree.
Multi-stage Dockerfile clones KamadoPool at a pinned SHA, builds
ckpool and kamado-api (with embedded Svelte UI), runtime image
supervises both processes via tini + wait -n. Config covers
bitcoind mainnet/testnet4 variant, payout address, coinbase tag,
vardiff knobs, and log level. Web UI interface only — stratum
:3333 requires a router port-forward or simpleproxy workaround
because StartOS 0.3.x does not forward raw TCP on LAN.
TODO before first build: pin KAMADO_REPO + KAMADO_SHA in the
Dockerfile to a pushed commit.
