ethernet 93679ef27d ci: run docker build on PRs + smoke test arm64
Adds `pull_request` trigger to docker-publish.yml so PRs that touch
Dockerfile / docker/ / pyproject.toml / uv.lock / the workflow itself
verify the image builds cleanly before merge.  Previously, Dockerfile
regressions (e.g. a stale uv.lock, a typo'd dep) would only surface
after merge when the docker-publish workflow ran on main.

Build-verify-only on PRs: the per-arch jobs run their `load: true`
build + smoke test, but the push-by-digest + artifact upload steps
remain gated on push-to-main or release.  The `merge` and
`move-latest` jobs stay excluded from PRs by their existing `if:`
gates, so :latest and SHA tags are never touched from PR runs.

Concurrency: PR runs use a PR-scoped group (`docker-<pr_number>`)
with `cancel-in-progress: true` so rapid pushes to the same PR
collapse to the latest commit.  Push/release runs keep
`cancel-in-progress: false` — every merge still gets its own
SHA-tagged image.

Also adds arm64 smoke tests (previously amd64-only): the image is
now built with `load: true` on arm64 too, then `docker run --help` +
`dashboard --help` smoke tests run identically on both arches.  Both
smoke test blocks were extracted into a new composite action at
`.github/actions/hermes-smoke-test` to keep the two jobs DRY.

# move-latest, because the ancestor check is the real safety mechanism
# and queueing is cheap (move-latest is a ~30s registry op).
