# -----------------------------------------------------------------------------
#
# Module design notes:
# This utility keeps project version metadata synchronized across the template.
#
# Responsibilities:
# - Read `__version__` from the package root `src/*/__init__.py`.
# - Update the `version` field in `pyproject.toml`.
# - Fail fast with explicit messages when expected files are missing.
#
# Scope boundaries:
# - It only updates version metadata.
# - It does not rename packages, edit lock files, or modify runtime config.
#
# Operational notes:
# - Intended for release/setup automation.
# - Safe to run repeatedly; output reflects the currently discovered version.
