feat(Sky): Replace Electron IPC service with Tauri service in build

Add Step 7 build hook in astro.config.ts that replaces the VS Code
ElectronIPCMainProcessService with TauriMainProcessService at build time.
This routes all IPC channel.call() invocations directly through Tauri
invoke to Mountain's WindServiceHandlers, eliminating the binary IPC
protocol entirely.

Part of the Electron workbench loading effort (see recent commits) to
enable the VS Code workbench to function within Tauri's WKWebView.
