📝 Walkthrough

Walkthrough

Plugin APIs now support layer-group creation and removal, while external native layer registrations can assign layers to groups. Existing group assignments persist when registrations are updated without a new group id, with regression coverage added.

Changes

Plugin layer-group support

Layer / File(s)	Summary
Layer-group API contracts and wiring packages/plugins/src/types.ts, apps/geolibre-desktop/src/hooks/usePlugins.ts	Plugin types declare optional group registration and management methods, which are wired to the application store.
External layer group propagation apps/geolibre-desktop/src/lib/external-native-layer.ts, tests/external-native-layer.test.ts	External native layers apply registration group ids and preserve existing group ids during updates, with test coverage for both behaviors.

Poem

I’m a rabbit with layers tucked neat,
Groups hop into the plugin’s seat.
Old group paths stay in view,
New APIs guide the queue,
Carrots bloom where layers meet.
