Two root causes of Joomla updater not finding MokoWaaS updates:
1. stabilityTagToInteger('development') looks for STABILITY_DEVELOPMENT
which doesn't exist → defaults to STABLE. Changed to 'dev' which
maps to STABILITY_DEV (0).
2. Missing <client> tag defaults to client_id=1 (administrator) in
Joomla's ExtensionAdapter. Packages install with client_id=0 (site).
Now adds <client>site</client> for all extension types.
Fixes: #129
