feat(Output): Add comprehensive Electron-to-Tauri polyfill layer

Implement a complete set of polyfills enabling VS Code to run in the Tauri browser environment without Electron:

- **ProcessPolyfill**: Node.js process object with argv, env, platform, versions, cwd(), hrtime(), cpuUsage(), exit()
- **FileSystemPolyfill**: fs module mapping readFile/writeFile/rmdir/etc to Mountain file:invoke commands
- **FileProtocolShim**: vscode-file://, vscode-userdata://, vscode-resource:// protocol handlers via fetch interception
- **ChildProcessPolyfill**: child_process spawn/exec/fork mapping to Mountain electron: commands
- **IPCRendererShim**: Electron ipcRenderer API with VS Code binary IPC protocol loopback for channel.call()
- **NativeModulePolyfill**: require('electron') shim providing ipcRenderer, webFrame, app, screen, shell, dialog, clipboard, nativeTheme
- **SharedProcessProxy**: Service proxies for extension host, search, debug, storage, update routing to Cocoon/Mountain via Tauri
- **TauriMainProcessService**: Drop-in replacement for ElectronIPCMainProcessService, routes getChannel().call() through Tauri invoke to Mountain
- **DevLog**: Tag-filtered development logging (vfs, ipc, config, etc.) with short/dedup modes

Also fix RestPlugin lazy loading: use if/try/catch instead of ternary to prevent ESM evaluation of the specifier when Compiler != Rest.

This is Phase 1-7 of Approach A3 — providing the Node.js/Electron API surface that VS Code's workbench expects, bridged to Tauri backend services.
