fix: use Rack::Files for Rack 3 compatibility#2
Merged
Conversation
Rack::File was removed in Rack 3 (it had been an alias for Rack::Files since Rack 2.1). Rack::Files works on both Rack 2 and 3, so this keeps the gem compatible across consumers while unblocking Rack 3 upgrades. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
