- Fix shebang in sanitize-logs.sh from #!/bin/bash to #!/usr/bin/env bash for NixOS compatibility - Update sanitizer defaults from 100/20 to 200/100 chars for better log readability - Fix CLI argument names in guide: --sync-bootstrap-relay -> --sync-bootstrap-relay-url - Fix CLI argument names in guide: --git-path -> --git-data-path These issues were discovered during first-time testing of the production sync testing guide.
