Ladybird 개발 방식을 바꾸기

Ladybird's shift to maintainer-only code merges addresses a fundamental challenge in open source security: AI tools now make superficially credible contributions indistinguishable from genuine ones, undermining traditional trust signals. For browser projects handling untrusted web input, a single sophisticated vulnerability introduced through AI-generated code could be catastrophic, making stricter governance essential for production-critical software.
