Fix mobile overflow for long names

[AgentGoose32]

Fixes #3

Summary

• adds a .min-width-0 utility used by existing flex layouts so long repository/package names can shrink on narrow screens
• lets badge text wrap and break anywhere, preventing long package coordinates from forcing mobile overflow

Validation

• git diff --check passed
• Full Rails/style build could not run locally because this repo's lockfile requires Bundler 4.0.10 while the system Ruby/Bundler cannot satisfy it
