v0.10.5

Added

• Pre-built multi-arch Docker images, published to GHCR on every version tag
  (.github/workflows/publish-image.yml) — linux/amd64 and linux/arm64 (Raspberry Pi and
  other ARM boards), tagged with the version, major.minor, and latest. This is an
  additional way to run Row Tracker, not a replacement — docker-compose.yml still defaults
  to build: . so the homelab deploy flow (deploy.sh) is unaffected. Self-hosters who'd rather
  docker compose pull than build locally can swap in image: ghcr.io/dsubtle1/row-tracker:latest
  — documented in the README under "Using the pre-built image instead of building locally."
