fix: regenerate package-lock.json with cross-platform deps

- Move renovate.json to .github/renovate.json
- Move electron-builder.yml to electron/electron-builder.yml
- Move electron.d.ts to electron/electron.d.ts
- Delete proxy.ts (unused dead code)
- Update package.json dist scripts with --config flag
- Use tsconfig.json files array for electron.d.ts (bypasses exclude)

Reduces git-tracked root files from 23 to 19.

-CRITICAL: You MUST provide the 'xml' argument in EVERY call. Do NOT call this tool without xml.
-
-When to use this tool:
-- Creating a new diagram from scratch
-- Replacing the current diagram with a completely different one
-- Major structural changes that require regenerating the diagram
-
-When to use edit_diagram instead:
-- Small modifications to existing diagram
-- Adding/removing individual elements
-- Changing labels, colors, or positions
-
-XML FORMAT - Full mxGraphModel structure:
-<mxGraphModel>
-  <root>
-    <mxCell id="0"/>
-    <mxCell id="1" parent="0"/>
-    <mxCell id="2" value="Shape" style="rounded=1;" vertex="1" parent="1">
-      <mxGeometry x="100" y="100" width="120" height="60" as="geometry"/>
-    </mxCell>
-  </root>
-</mxGraphModel>
-
-LAYOUT CONSTRAINTS:
-- Keep all elements within x=0-800, y=0-600 (single page viewport)
-- Start from margins (x=40, y=40), keep elements grouped closely
-- Use unique IDs starting from "2" (0 and 1 are reserved)
-- Set parent="1" for top-level shapes
-- Space shapes 150-200px apart for clear edge routing
-
-EDGE ROUTING RULES:
-- Never let multiple edges share the same path - use different exitY/entryY values
-- For bidirectional connections (A↔B), use OPPOSITE sides
-- Always specify exitX, exitY, entryX, entryY explicitly in edge style
-- Route edges AROUND obstacles using waypoints (add 20-30px clearance)
-- Use natural connection points based on flow (not corners)
-

-- Shapes: rounded=1; fillColor=#hex; strokeColor=#hex
