fix: quality-rails Commander version mismatch crashes mosaic quality-rails

CLI uses Commander 13, quality-rails used 12. The `_prepareForParse`
method (v13-only) was called on a v12 Command object via `addCommand`.

Fix: export `registerQualityRails(parent)` that registers subcommands
directly on the caller's Commander instance, avoiding cross-package
command sharing. Bump quality-rails commander to ^13.0.0.

Bump: cli/mosaic 0.0.10, quality-rails 0.0.3.
