"""Release preflight checks - no ComfyUI required.

Run from anywhere:  python scripts/release_preflight.py

Checks:
  1. pyproject.toml has no UTF-8 BOM. tomllib rejects a BOM, and both
     ComfyUI-Manager and the Comfy Registry parse the file with it, so a
     BOM breaks installs silently.
  2. AUSBOSS_JS_VERSION in js/shared/index.mjs equals the pyproject
     version, so the stale-browser warning never fires on a fresh install.

Exit code 0 = ready to release, 1 = problems printed below.
