fix: security hardening, tests, docs for Electron desktop & memory optimization

## Security Fixes - Sanitize OMNIROUTE_MEMORY_MB with parseInt + range validation (64-16384) to prevent command injection via spawn() args - Validate URL protocol in shell.openExternal (http/https only) to prevent RCE in Electron renderer compromise - Bump default memory from 256MB to 512MB ## Electron package-lock.json - Added to .gitignore (5278 lines removed from tracking) ## Test Suite (64 tests, 9 suites) - electron-main.test.mjs: URL validation, IPC channels, window handler - electron-preload.test.mjs: channel whitelist, API surface, open-external - cli-memory.test.mjs: injection prevention, boundary values, .env parsing ## Documentation - Desktop App section added to all 30 READMEs (9 fully translated) - USER_GUIDE.md updated with 512MB default - .env.example reflects new defaults
