- kiosk.Client reads the registry API v1 over fetchguard (trusted mode,
4 MiB, 10 s, no redirects); kiosk.RegistryURL reads plugins.registry_url
(default https://summercms.io, empty disables)
- build.PlanInstall/ApplyInstall pick the newest release the effective
framework satisfies (or a pin), validate registry strings, go get it and
append it to summer.yaml
- summer.yaml edits (plugin:add and plugin:install) keep comments and
blank lines
- TestInstallSmoke/module installs from a file:// GOPROXY and builds
