### What needs to get done Generic InitCommand should be created, so all the crafts can use it, that allows: - specifying `name` as an option and `project_dir` as a positional argument (the way `cargo` / `uv` works) - use Jinja2 for templates - support profiles e.g. by searching `templates` for subdirectories and listing them as options - by default it will allow to be run in non-empty directory, as long as it creates only new files (no-overrides). This behavior may be overwritten (opt-out), so charmcraft will be able to error-out in non-empty directory ### Why it needs to get done Currently all the applications have a separate way of handling `init`. We should create a generic version, that everyone can use. It will enable create specific profiles in snapcraft, make our codebase smaller and it will be easier to maintain in the single place.
