An alternative RubyGems loader that pulls in only the minimal components required at runtime, instead of the full RubyGems stack used during gem installation. Ideal for use with standalone bundles, allowing RubyGems to be disabled via --disable-gems while still providing essential runtime functionality.

1. Add rubygems/runtime to Gemfile

2. Use bundle install --standalone, which generates a freestanding bundler/setup.rb that doesn't depend on RubyGems or Bundler

3. Disable RubyGems by either running the Ruby program via ruby --disable-gems or by adding --disable-gems to RUBYOPT:

   ruby --disable-gems script/rails server

   -or-

   export RUBYOPT="--disable-gems"
   
   script/rails server

Add install-gems.sh from Bundler Standalone Improvements and use it to install gems, rather than invoking bundle directly.
