fix: prevent brew bundle hanging on large cask installs

Browse Source 
HOMEBREW_NO_QUARANTINE=1 — skips the post-install xattr quarantine walk
  that Gatekeeper runs on every binary in the app bundle. For large apps
  like WhatsApp (237 MB, many nested binaries) this walk blocks for several
  minutes. Apps will show the standard one-time Gatekeeper dialog instead.

HOMEBREW_NO_INSTALL_CLEANUP=1 — skips per-package cache cleanup after each
  install. A single brew cleanup already runs in ssr-sync afterwards.

mdimport — now runs in background (&) so Spotlight indexing never blocks
  the restore flow.
