Follow-up on the re-review's two optional notes: - Set `ENV HOME=/home/node` so the runtime-state dir (core/storage/store-io.ts resolves it from HOME) is explicit, rather than relying on the "." → WORKDIR fallback that happens to work because Docker doesn't set HOME on USER. - Document that the HEALTHCHECK assumes the default --web mode; suggest `--no-healthcheck` for --cli/--tui runs (no web server to probe). Re-verified: build ok, HOME=/home/node, runs as node (uid 1000), `/` → 200, health → healthy.
