0.3.7 — Unreal plugin renders native: right-click actions + dock tab, real icons

Plugin contributions gain named host icons, a working-folder context slot, and
bottom-dock panels. The Unreal plugin (1.2.0) now puts Launch / Build Solution
in the folder right-click menu with the UE + hammer icons and its log in a
bottom-dock "Unreal" tab — where they lived before extraction — instead of
emoji entries in Tools. Plugin is backward-compatible (falls back to menu/view
on 0.3.6 hosts).
