- Build stage keeps Bun for fast installs; appends `npm install --package-lock-only`
to generate an ephemeral package-lock.json immediately after `bun run build:all`.
- Runtime stage removes BUN_VERSION ARG/ENV, the bun.sh curl install, and
`bun install --frozen-lockfile --production`. Replaces with:
COPY --from=build /app/package.json /app/package-lock.json ./
RUN npm ci --omit=dev --ignore-scripts
- --ignore-scripts rationale: postinstall (scripts/postinstall.js) writes ~/.ccs/
config — not needed in Docker context. bcrypt v6+ is pure-JS, no native compile.
- package-lock.json already in .gitignore (line 33); never committed.
- docker/Dockerfile.integrated unchanged — no Bun present there (alpine + npm).
- Targets: image size reduction >= 300 MB by eliminating ~130 MB Bun binary + installer.
