fix: electron renderer with nodeintegration enabled and sandbox disabled

[kumburovicbranko682-boop]

🔒 Security Fix

Problem

The launcher window runs with nodeIntegration: true and sandbox: false as documented in the inline comment.
This means any JavaScript executing in that renderer (including third-party Raycast extensions) has unrestricted
access to Node.js APIs — fs, child_process, crypto, etc. If an extension contains an XSS vulnerability, or if
an attacker compromises a Raycast store extension, they gain full filesystem and process access on the host machine.

Electron's official security documentation explicitly warns against this configuration. The recommended approach
is to use contextBridge + preload scripts to expose only the specific APIs extensions need, rather than
granting blanket Node access.

The SECURITY.md mentions an "Electron Security Architecture" section but does not disclose this risk.

Severity: high
File: vite.config.ts

Solution

Refactor to use Electron's recommended security model:

1. Set nodeIntegration: false and sandbox: true in the BrowserWindow webPreferences.
2. Create a preload script that uses contextBridge.exposeInMainWorld() to expose only the specific
   Node APIs required by Raycast extensions (e.g., a controlled require shim or a curated API surface).
3. Use ipcRenderer/ipcMain for privileged operations, with an allowlist of valid IPC channels.

Example BrowserWindow config:

Changes
