feat(shaders_lab): visual node editor (imgui-node-editor) + multi-source

- cpp/vendor/imgui-node-editor: vendorized thedmd/imgui-node-editor v0.9.4 - cpp/functions/gfx/dag_node_editor: new visual pipeline editor replacing dag_panel - DagStep: source_ids[4] + editor_pos + editor_uid (multi-input support) - DagNodeDef: num_inputs explicit; circle reclassified as Op - dag_compile: N inputs per node, topological ordering preserved - main: use node editor; destroy on shutdown - patch imgui_extra_math.inl: guard operator*(float, ImVec2) for imgui >= 18955 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
