The official golang images set GOTOOLCHAIN=local, so a base older than the
governing go.mod `go` directive fails hard instead of fetching a toolchain:
go: go.mod requires go >= 1.26.5 (running go 1.26.4; GOTOOLCHAIN=local)
docker/Dockerfile.multi-node sat on golang:1.24.5-alpine, two minor versions
under the root go.mod floor of 1.26.4. Dockerfile, deploy/testnet/Dockerfile
and Dockerfile.dvenue were at 1.26.4 — exactly at the floor, with no headroom.
Two orthogonal halves:
1. pin every Go builder base to the latest stable patch, 1.26.5, so the
images carry current compiler and stdlib security fixes;
2. set GOTOOLCHAIN=auto in every Go builder stage, so a future floor bump
downloads a checksum-verified toolchain rather than hard-failing.
Dockerfile and deploy/testnet already had it; multi-node and dvenue
did not.
Half 2 is not hypothetical here: sdk/lx-trading-go/go.mod already declares
go 1.26.5, above the root module's 1.26.4, so a submodule build under
GOTOOLCHAIN=local would die at exactly this error.
The root `go` directive stays at 1.26.4 on purpose — raising it pushes a hard
patch-level floor onto every consumer. A newer toolchain building an older
directive is always valid.
docs/Dockerfile is untouched: it builds static docs and compiles no Go.
