v0.0.29

Changed

• App::loadAddons() automatically aliases every phlat//site/ addon to its folder name (e.g. phlat/admin → @admin) : explicit alias config is now only needed to override that default or to alias an external addons/{vendor}/{name} addon. Site addons win the alias on a name collision with a built-in.
• phlat/config.json's addons entries dropped their now-redundant alias keys; phlat/admin and phlat/git are listed explicitly alongside clockwork/ui.
• Admin layout's hardcoded $admin->file(...) asset references switched to f('/admin/...').
