omarchy font set resets foot terminal font size to 9, discarding a previously-set size

[Fiorina161]

What happened

Running omarchy font set <name> resets the foot terminal's font size back
to 9, discarding whatever size was previously set (e.g. via
omarchy display text size <px>).

This is specific to foot. For alacritty, kitty, and ghostty, omarchy-font-set
only rewrites the font family and leaves the size line untouched. But for
foot it rewrites the whole directive with a hardcoded size:

if [[ -f ~/.config/foot/foot.ini ]]; then
  sed -i "s/^font=.*/font=$font_name:size=9/g" ~/.config/foot/foot.ini
fi

(from omarchy-font-set, the binary behind omarchy font set)

Expected

Changing the font family should not change the font size on any terminal.
Foot should behave like the other three: preserve the existing :size=N
suffix and only swap the family.

Steps to reproduce

omarchy display text size 14   # sets foot.ini to font=<Family>:size=11
omarchy font set "JetBrainsMono Nerd Font"
grep '^font=' ~/.config/foot/foot.ini
# => font=JetBrainsMono Nerd Font:size=9   (size silently reverted; expected size=11)

System

• Omarchy version: 4.0.1-1
• Kernel: Linux 7.1.9-arch1-2 x86_64
• Terminal: foot

Suggested fix

Preserve the existing size instead of hardcoding it:

if [[ -f ~/.config/foot/foot.ini ]]; then
  sed -i -E "s/^font=[^:]*(:size=[0-9.]+)?/font=$font_name\1/" ~/.config/foot/foot.ini
fi
