# Self-update: pull latest code from the OVH Gitea (146.59.87.168:3000) and apply
# Designed to run on installed Archipelago nodes (as archipelago user)
#
# Usage:
#   ./self-update.sh              # Check + apply if available
#   ./self-update.sh --check      # Check only, don't apply
#   ./self-update.sh --force      # Apply even if already up to date
#
# The script:
#   1. Pulls latest code from origin (146.59.87.168:3000)
#   2. Builds the Rust backend (release mode)
#   3. Builds the Vue frontend (production mode)
#   4. Installs the new binary and web UI
#   5. Restarts the archipelago service
#   6. Verifies health after restart
