# Calculates version based on current stable, not semantic-release's predicted next version.
# Pattern: {stable}-dev.{N} where N increments for each dev release.
#
# Example:
#   main at v6.7.1 → dev releases: 6.7.1-dev.1, 6.7.1-dev.2, ...
#   main releases v6.7.2 → dev releases: 6.7.2-dev.1, 6.7.2-dev.2, ...
