feat(lsp): call hierarchy prepare / incoming / outgoing (0.8)

Expose LSP call hierarchy over a lightweight textual call graph of known functions and Name( call sites across the workspace. - prepareCallHierarchy on func decl or call site - incomingCalls / outgoingCalls with fromRanges - smoke_lsp_call_hierarchy + test-lsp wiring
