# Purpose: Bump version, create git tag, and optionally push to remotes
# Usage: ./bump-version <new-version> [--push]
# Example: ./bump-version 1.0.5
#          ./bump-version 1.0.5 --push
#
# This script:
#   1. Updates the VERSION file
#   2. Updates the spec file Version: line
#   3. Updates debian/changelog (if dch is available)
#   4. Commits the changes
#   5. Creates a git tag (vX.Y.Z format)
