reinstate fzf over gum filter for:

- shell integration
  - fuzzy completion on `cd <stuff>**` -> Tab
  - hotkeys
- file/folder previews
- working with enhancd (`cd`): https://codeberg.org/kiara/cfg/issues/130
- supporting pageup / pagedown: charmbracelet/gum#499
- actually allowing querying out of order
  - charmbracelet/gum#500
  - anyrun-org/anyrun#135
