fix(docker): build the image from source so a fresh clone builds

The Dockerfile copied a pre-built binary from dist/<arch>/artex into the
runtime image, but dist/ is git-ignored, so a fresh `git clone` has no such
file and `docker compose up -d --build` fails with
"/dist/amd64/artex: not found".

Build the binary from source in the image instead: a Node 22 stage runs the
frontend static export, a Go 1.26 stage runs build.sh with the same flags as
the release binaries job (CGO-free cross-compile, -trimpath, pinned version),
and the runtime stage copies the compiled binary. No build-context binary is
needed, so a clean clone builds.

Drop the now-obsolete dist/ warning in install.sh.
