chore(release): bump version to 4.3.2

The daemon already has automatic config file watching and reloads changes
without requiring a restart. Updated action handler messages to correctly
reflect this behavior.

Changed:
- 'Restart service to apply changes: nupst service restart'
  → 'Changes saved and will be applied automatically'

The config file watcher (daemon.ts:986) uses Deno.watchFs() to monitor
/etc/nupst/config.json and automatically calls reloadConfig() when changes
are detected. No restart needed.
