✅ Suggested fix for Nokogiri build error on Termux (Android)

[Githu836]

Workaround for Nokogiri install error on Termux (Android)

Nokogiri fails to build native extensions on Termux due to bundled libraries
(libxml2 / libxslt / gumbo) not compiling correctly on Android.

To fix this, run the following commands once:

pkg install libxml2 libxslt
bundle config set build.nokogiri --use-system-libraries
bundle config set force_ruby_platform true

Then repeat the installation (bundle install).

This forces Nokogiri to use Termux system libraries and avoids
building bundled static libraries that cause gumbo.c errors.
