Note

Low Risk
Routine pinned-engine and semver bump only; reachability results may differ slightly with the new Coana version but no Python CLI logic changed.

Overview
Releases Socket Python CLI 2.10.4 by bumping the shipped reachability engine pin from @coana-tech/cli 15.11.0 to 15.11.3.

The default used when --reach runs without --reach-version is updated in DEFAULT_COANA_CLI_VERSION, the CLI reference docs, and the changelog; pyproject.toml, __init__.py, and uv.lock reflect the new package version. No other behavior or dependency changes in this diff—engine details are in the reachability analysis changelog.
