Closes#1964.
- README's Docker recipes dropped v1's `127.0.0.1:` prefix, so
`-p 6274:6274` published the Inspector on every host interface. The
container's `HOST=0.0.0.0` governs the container's interfaces, not the
host's, so `DANGEROUSLY_BIND_ALL_INTERFACES` never covered this. Verified
against a real container: from a LAN peer, `GET /` served the injected
`MCP_INSPECTOR_API_TOKEN`, and that token then unlocked `/api/*` with no
`Origin` header (server.ts:241 allows origin-less requests). Restore the
prefix on both recipes, on the port-remap examples, and in the web README.
- Adding a server failed inside the container the moment you mounted a
volume to keep it. Docker seeds a named volume's ownership from the
image's directory at the mount point, and creates it `root:root` when
that directory is absent — so the non-root `node` user got
`EACCES ... open '/home/node/.mcp-inspector/mcp.json.tmp-*'`. Create the
dir in the image, owned by `node`, and document the volume recipe (plus
the bind-mount `--user` caveat) — without a volume the catalog lives in
the writable layer and `--rm` throws it away.
