# StepProbe — Background Runner
#
# Launches the full pipeline in the background with:
# - nohup for persistence after SSH disconnect
# - tmux session for easy re-attach
# - Email notification on completion (optional)
#
# Usage:
# bash scripts/run_background.sh # default full run
# bash scripts/run_background.sh --quick # quick test
# bash scripts/run_background.sh --tmux # use tmux instead of nohup
# bash scripts/run_background.sh --notify email # send email on completion
