Alpine uses musl libc; better-sqlite3 has no pre-built musl binaries so it always compiles from source (installs 300 MB of gcc/g++/python3, takes 3-5 min). node:22-slim (Debian) has glibc so prebuild-install downloads a pre-built binary instead — build stays under 1 minute. Changes: - Both stages: node:22-alpine -> node:22-slim - deps stage: remove apk/build-tool installation (not needed) - runtime stage: remove apk libstdc++ install (present in debian-slim) - HEALTHCHECK: wget -> node built-in http (wget absent from debian-slim) - docker-compose.yaml: same healthcheck fix
