REM update.bat — One-click update for HOT-Step-CPP source builders.
REM
REM Pulls latest code, verifies integration hooks, rebuilds everything
REM incrementally. Reuses existing build infrastructure (build.cmd patterns).
REM
REM Usage:
REM   update.bat              Incremental update (safe, default)
REM   update.bat --force      Reset local changes before pulling (with confirmation)
REM   update.bat --clean      Force clean engine rebuild (warning: CUDA = 20+ min)
REM   update.bat --skip-engine  Skip engine rebuild (UI/server changes only)
REM   update.bat --help       Show this help
REM
REM For portable release users: you don't need this script.
REM   Download new releases from GitHub instead.
