The image switched to the node user (uid 1000) at build time, so a host
folder mounted at /data kept its host ownership and SQLite failed with
SQLITE_CANTOPEN in a restart loop. Named and anonymous volumes worked only
because Docker copies the image's /data ownership into them.
The container now starts as root, hands DATA_DIR and the database folder
to node (only entries not already owned by it), and execs the app via
setpriv as node. Containers started with an explicit `user:` skip this.
Adds a CI step that runs the image with a host-owned bind mount.
