Address PR #1648 review:
- Bump the GHCR action majors to match current v1 (docker/login-action v4,
docker/metadata-action v6, docker/setup-buildx-action v4,
actions/attest-build-provenance v4) to avoid Dependabot churn.
- Make the image tags explicit (`type=semver` + `flavor: latest=true`) instead
of relying on `flavor.latest=auto`, so a release lands both the version tags
and `:latest` — the README's bare `ghcr.io/…/inspector` URL won't 404.
- Run the container as the non-root `node` user with /home/node as workdir (its
writable home is where the inspector stores the catalog / OAuth state).
- Add a HEALTHCHECK that probes `/` via Node's global fetch (no curl in slim).
- Trim specification/ and docs/ from the build context. (test-servers/ stays —
`tsc -b` typechecks the integration tests that import its alias, so excluding
it breaks the build.)
Re-verified locally: `docker build` succeeds, the container runs as uid 1000
(node), serves `/` (200), and the HEALTHCHECK reports healthy.

v1 published a container image but v2 arrived with no Dockerfile (the
client/server/cli layout is gone). Add a v2 image for the single-package /
launcher architecture and wire the release-gated GHCR publish job.
- `Dockerfile`: two-stage build — stage 1 installs + `npm pack`s the publishable
tarball; stage 2 `npm install -g`s that tarball, so the image ships the exact
same artifact as npm with a clean `mcp-inspector` bin. Defaults to `--web` on
`0.0.0.0:6274`, browser auto-open off. `.dockerignore` keeps the context lean
and forces a clean in-container install/build.
- `publish-github-container-registry` job in main.yml (ported from v1):
release-gated, multi-arch (amd64/arm64) build+push to GHCR with a provenance
attestation. Independent of the npm `publish` job.
- README: document the image + how to run it; the release section now covers
both publish jobs.
Verified locally: `docker build` succeeds, the container serves `/` (HTTP 200
with the injected token) and dispatches `--cli` / `--tui`.
