- Fix 1: Parse -b/--branch and --mariadb-version with while-loop so only next token is used
(avoids Branch_Name becoming 'v2.5.5-dev --mariadb-version 12.3')
- Fix 2: Default Git_User to master3395 in Pre_Upgrade_Setup_Git_URL (04_git_url, monolithic)
- Fix 3: upgrade.py uses CYBERPANEL_GIT_USER for git clone (default master3395);
export CYBERPANEL_GIT_USER before upgrade.py in 08_main_upgrade and monolithic
- Fix 4: --mariadb-version already supported in 05_repository.sh (MARIADB_VER_REPO)
- cyberpanel_upgrade.sh is now a loader that sources upgrade_modules/*.sh
- When upgrade_modules/ is missing (e.g. one-liner), loader downloads modules from GitHub
- All modules kept under 500 lines for easier debugging
- cyberpanel_upgrade_monolithic.sh preserves full original script
- to-do/UPGRADE-MODULES-DESIGN.md documents module layout
