fix(gui): merge Silo toolbar into File toolbar via origin system (#65)

- Remove separate Silo workbench toolbar (now redundant)
- Remove SiloMenuManipulator (Std commands already delegate to origins)
- Remove Silo_ToggleMode (origin selector handles mode switching)
- Register Silo origin at startup via Create module
- Update docs to reflect unified origin architecture

 **Goal:** Silo commands available globally, not just in the Silo workbench.
 
-**Implementation:** `SiloMenuManipulator` in `src/Mod/Create/InitGui.py` uses `FreeCADGui.addWorkbenchManipulator()` to inject Silo commands into the File menu and toolbar across all workbenches. `Silo_ToggleMode` provides a one-click swap of Ctrl+O/S/N between standard FreeCAD and Silo file commands.
+**Implementation:** The unified origin system (`FileOrigin`, `OriginManager`, `OriginSelectorWidget`) in `src/Gui/` delegates all file operations (New/Open/Save) to the selected origin. Standard commands (`Std_New`, `Std_Open`, `Std_Save`) and origin commands (`Origin_Commit`, `Origin_Pull`, `Origin_Push`, `Origin_Info`, `Origin_BOM`) are built into the File toolbar and menu. The Silo workbench no longer has its own toolbar — it only provides a menu with admin/management commands.
