- Remove consecutive breach tracking for statement queue (immediate alerts) - Consolidate script initialization into init_script() function - Remove unused helper functions (send_ok, run_as_hana_user, get_mount_point) - Flatten sld_watchdog.sh structure by removing main() wrapper - Remove state directory and lock directory configuration from hana.conf - Simplify alert messages to include threshold values This continues the simplification effort from previous commits by removing stateful tracking mechanisms and streamlining the monitoring logic for easier maintenance.
