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`.
