Closes: #177 (CRITICAL — Dockerfile runs as root)
Dockerfiles changed:
- workspace-server/Dockerfile (platform-only): addgroup/adduser + USER platform
- workspace-server/Dockerfile.tenant (combined Go+Canvas): addgroup/adduser + USER canvas
+ chown canvas:canvas on canvas dir so non-root node process can read it
- canvas/Dockerfile (canvas standalone): addgroup/adduser + USER canvas
- workspace-server/entrypoint-tenant.sh: update header comment (no longer starts
as root; both processes now start non-root)
The entrypoint no longer needs a root→non-root handoff since both the Go
platform and Canvas node run as non-root by default. The 'canvas' user owns
/app and /platform, so volume mounts owned by the host's canvas user work
without needing a root init step.
