REM  build_all.cmd  —  Build Tlamatini end-to-end.
REM
REM  IMPORTANT: build.py must be launched with a SEPARATE *system* Python, NOT
REM  the carried "<repo>\python". build.py provisions/copies that carried tree
REM  itself (ensure_local_build_python + bundle_carried_python) and ABORTS early
REM  if it detects it was started with it:
REM      "ERROR: build.py was launched WITH the carried Python (...). Aborting."
REM  That guard is exactly why the old version of this script failed while the
REM  manual "python build.py ..." (which used C:\Program Files\Python312) worked.
REM
REM  - Works from ANY location: it resolves its own folder.
REM  - Runs, in order:  1) build.py --self-modify   2) build_uninstaller.py
REM                     3) build_installer.py
