Build Claude Code Haha desktop for Linux with Electron Builder.

Usage:
  ./desktop/scripts/build-linux.sh [extra electron-builder args...]

Environment:
  LINUX_ARCH=x64|arm64  Target architecture. Defaults to x64.
  LINUX_TARGETS         Electron Builder Linux targets. Defaults to "AppImage deb".
  SKIP_INSTALL=1        Skip `bun install` in the repo root and desktop app.
  REBUILD_NATIVE=1      Run `electron-builder install-app-deps` before packaging.
  SKIP_PACKAGE_SMOKE=1  Skip package-smoke verification after copying artifacts.
  OPEN_OUTPUT=1         Open the canonical artifact output directory after a successful build.
