Publish operational files with the npm package

[JSONbored]

Problem: The published npm package's file list excludes DEPLOYMENT.md, the docs directory, the Dockerfile, and the schema directory — an npm install -g user (the README's own quickstart path) has no access to any of this operational material without separately visiting the GitHub repo.

Area: AMS / Self-host

Proposal: Include these files in the package's published file list.

Deliverables:

• A published package that includes its own operational documentation.
