bug: `eza -alF .` regressed with clap

[danielzgtg]

My .bashrc has alias ls='eza -alF', converted from exa -alF, converted from ls -alF. Commit fc0ba14 caused that backwards compatibility with GNU ls and exa to stop working.

Expected behavior

I noticed that previously eza: Flag -F cannot take a value, but now it can take a value. I don't know what should happen to users who installed it starting in 2026 and expect it to continue taking a value.

Actual behavior

home@daniel-desktop3:~$ eza --version
eza eza - A modern, maintained replacement for ls
v0.23.5 [+git]
https://github.com/eza-community/eza
home@daniel-desktop3:~$ eza -alF /
error: invalid value '/' for '--classify [<WHEN>]'
  [possible values: always, auto, never]

For more information, try '--help'.

I want eza to continue to be a drop-in replacement for exa, if not gnuls. Something that worked before 2025 should continue working.
