The `--with-deps` flag installed font rendering libraries (libfreetype6,
libfontconfig1) but no actual font files, causing CJK characters and
emoji to render as invisible/tofu on headless Linux systems.
Add font file packages for all three supported package managers:
- apt: fonts-noto-color-emoji, fonts-noto-cjk, fonts-freefont-ttf
- dnf: google-noto-cjk-fonts, google-noto-emoji-color-fonts, liberation-fonts
- yum: google-noto-cjk-fonts, liberation-fonts
Closes#1001
