fix: trigger live filter when navigating history

History navigation (Up/Down arrows) now triggers the live filter
preview immediately, just like typing characters does. Previously,
selecting a filter from history required editing it first before
the filter would apply.

This fix adds HistoryUp and HistoryDown events to the special
handling in main.rs that triggers the background filter thread
when the input buffer changes.
