Google rewrites giflib from C to Rust using Gemini and differential fuzzing

Google ported the ~3,000-line giflib C library to memory-safe Rust using Gemini and an autonomous feedback loop. The ABI-compatible Rust build passed 200 million differential fuzzing iterations and proved immune to CVE-2026-26740 before disclosure. The result is open-sourced as giflib-rs.
