- ninja login forces account selection (interactive when >1); creds now
carry ActiveAccountID/Slug. New `ninja account` group.
- ninja plugin list / delete / delete-version split public vs active-account
@private sections; `publish --private` is sticky in plugin.mod.
- GetPluginRequest gains active_account_id so @private resolution works
alongside the public (scope, name) path.
- publish auto-commits a dirty plugin.mod (path-scoped, leaves other staged
paths alone) so the bump→publish loop never trips the dirty check.
--allow-dirty is replaced with --strict (default now ships dirty trees
via stash-create).
- bump auto-commits its plugin.mod write with `bump to X.Y.Z`; --no-commit
opts out.
- Design doc updated to match the new defaults.
