feat(electron): add desktop application support with electron (#344) * feat(electron): add desktop application support with electron - implement complete Electron main process architecture with window management, app menu, IPC handlers, and settings window - integrate Next.js server for production builds with embedded standalone server - add configuration management with persistent storage and env file support - create preload scripts with secure context bridge for renderer communication - set up electron-builder configuration for multi-platform packaging (macOS, Windows, Linux) - add GitHub Actions workflow for automated release builds - include development scripts for hot-reload during Electron development * feat(electron): enhance security and stability - encrypt API keys using Electron safeStorage API before persisting to disk - add error handling and rollback for preset switching failures - extract inline styles to external CSS file and remove unsafe-inline from CSP - implement dynamic port allocation with automatic fallback for production builds * fix(electron): add maintainer field for Linux .deb package - add maintainer email to linux configuration in electron-builder.yml - required for building .deb packages * fix(electron): use shx for cross-platform file copying - replace Unix-only cp -r with npx shx cp -r - add shx as devDependency for Windows compatibility * fix(electron): fix runtime icon path for all platforms - use icon.png directly instead of platform-specific formats - electron-builder handles icon conversion during packaging - macOS uses embedded icon from app bundle, no explicit path needed - add icon.png to extraResources for Windows/Linux runtime access * fix(electron): add security warning for plaintext API key storage - warn user when safeStorage is unavailable (Linux without keyring) - fail secure: throw error if encryption fails instead of storing plaintext - prevent duplicate warnings with hasWarnedAboutPlaintext flag * fix(electron): add remaining review fixes - Add Windows ARM64 architecture support - Add IPC input validation with config key whitelist - Add server.js existence check before starting Next.js server - Make afterPack throw error on missing directories - Add workflow permissions for release job --------- Co-authored-by: dayuan.jiang <jdy.toh@gmail.com>
