feat(lsp): interface dispatch in call hierarchy (0.11)

Index interface methods and extend Type for Trait relations so call hierarchy can show implementors as outgoing targets and .Method call sites as incoming. - interface I { func M } + extend T for I tracking - prepare/outgoing/incoming with data Iface#Method - smoke_lsp_iface_hierarchy (Drawable.Draw ↔ Circle / Render)
