feat($skill): add skill list to State + bootstrap fetch for popover data

- State.skill[] added for available skill list (name, description, location, content)
- Bootstrap: input.sdk.app.skills() fetch with catch (non-blocking)
- child-store: skill: [] in initial state
- test: skill: [] in baseState
- This provides the data source for the $ skill popover
