Ship docs/ in the image, so /docs is not empty in production

[ralyodio]

/docs/api, /docs/cli, /docs/mcp and /docs/plugins all answer 404 on tsbb.dev right now, from the moment #3 deployed.

.dockerignore excluded docs/, so the built image has no documents to render. The index still answers a healthy 200 — it renders its "This install was deployed without its docs directory" fallback — which is why the deploy looked fine.

docs        200      <- the empty-state fallback
docs/api    404
docs/cli    404
docs/mcp    404

The guard

Nothing that boots the app in a checkout could have caught this: the files are right there, and all ten docs tests passed. So the guard goes on the thing that was actually wrong. test/docs.test.ts now reads .dockerignore and fails if docs/ is excluded — verified by re-adding the line and watching it go red:

✖ ships the documents in the image
  AssertionError: .dockerignore excludes docs, so the built image would serve no documentation

The route also warns at boot when the directory is missing. A documentation site that silently serves nothing is a failure with no symptom anyone would notice from the outside, and it deserves a line in the log.

Testing

146 tests, up from 145. pnpm typecheck clean.

Note CI cannot run — the account is locked over a GitHub Actions billing issue, so every job dies in a few seconds with "The job was not started because your account is locked due to a billing issue." That is unrelated to this change; local runs are the evidence.
