#!/usr/bin/env bash
#
# bump-version.sh — bump version numbers across all declared files,
# with drift detection and repo-wide audit for missed files.
#
# Usage:
#   bump-version.sh <new-version>   Bump all declared files to new version
#   bump-version.sh --check         Report current versions (detect drift)
#   bump-version.sh --audit         Check + grep repo for old version strings
