feat(deploy): DGX standalone compose (ai-server only, 24855) + confirmed-topology runbook

[dhkim-kr]

Why

#71 was merged at head e4bb0bb, moments before commit 5388210 (the DGX deployment file) reached the branch — same merge-window race as #70/#71. This PR carries that stranded commit plus a deployment-blocking .dockerignore fix found during the pre-deploy file audit. Base is Master; single merge; nothing else to merge first.

Commit	File	What
5388210	infra/deploy/docker-compose.dgx.yml (new)	Standalone DGX compose (never combined with dev compose): ai-server only — no postgres/api (DB container :28881 already runs on the DGX, admin-managed), distinct project+container names (neuro-sync-ai-dgx/ns-ai-server-dgx), production CMD (no --reload, no source mounts), env_file .env with PROMPTS_BASE_DIR re-pinned to baked /app/prompts, extra_hosts host-gateway DB-hairpin fallback, restart: unless-stopped, port 24855:8001
5388210	docs/ai/deployment_integration_plan.md §3	Confirmed topology (one DGX Spark 223.194.33.26: DB :28881 running / ai-server :24855 to deploy) + 4-command runbook + backend base URL http://223.194.33.26:24855
1d8449e	.dockerignore	Build-blocker fix: the pre-existing docs exclusion removes the whole docs tree from the build context, so the Dockerfile's COPY docs/ai/prompts /app/prompts (added in #71) would fail the DGX image build — never caught locally because the dev workstation has no docker. Negations !docs/ai/prompts(/**) re-include only the prompts subtree. Also excludes _archive (42MB / 1,856 files) from the build context.

After merge — on the DGX (account that runs the DB container)

git clone https://github.com/Neuro-AI-Lab/neurosync.git && cd neurosync   # or git pull
# place apps/ai-server/.env (copied from dev workstation; never committed)
docker compose -f infra/deploy/docker-compose.dgx.yml up -d --build
curl -s localhost:24855/health

Close — supersession map (filemanager, 8-PR 순차 머지 완료 후)

본 PR(#72, deploy/backend-integration-surface)의 산출물은 아래와 같이 Master에 이미 상위집합/현행화 형태로 랜딩되어 close합니다.

#72 산출물	상태	상위집합/현행화 근거
DGX standalone compose (infra/deploy/docker-compose.dgx.yml 등)	상위집합	#79(feat(api): F1~F3 연동 배선 + hospitals-map + DGX 배포 토폴로지)가 동일 compose 파일을 포함해 Master에 랜딩 (merge SHA 3ed0d3d)
배포문서 §3 (docs/ai/deployment_integration_plan.md 등)	현행화	#83(docs(ai): F1~F5 통합 문서 정리)이 배포 현황을 최신화해 Master에 랜딩 (merge SHA 1fa5599)
.dockerignore negation (!docs/ai/prompts, Dockerfile의 COPY docs/ai/prompts 성립 조건)	전제 소멸 — 이식 불요	ADR-041 T4가 #80(fix(ai-server): BUG-069~085 F1 자율대화...) 머지로 랜딩되며 apps/ai-server/Dockerfile이 COPY apps/ai-server/prompts /app/prompts로 이전, 빌드 경로가 docs/ai/prompts를 완전히 이탈함(merge SHA f6d7946). 현 Master .dockerignore에 이미 이 사유가 주석으로 명시되어 있어 손실 없이 close 가능
