libghostty-vt 1.0 locks ABI stability

This is bigger than a terminal release: it commoditizes one of the most neglected layers in developer tooling. libghostty-vt lets teams stop reimplementing terminal semantics and focus on interfaces, workflows, and agent integrations.

• –ABI stability, signed tarballs, SONAMEs, pkg-config, and CMake metadata remove major adoption blockers for distributions.
• –JetBrains’ migration puts libghostty underneath terminals used by more than 12.5 million active users.
• –Support across Linux, macOS, Windows, Android, iOS, FreeBSD, WebAssembly, and bare-metal targets makes it unusually portable.
• –Neovim, KDE’s Kwi, Ghostel, cmux, and other projects show the library becoming shared infrastructure rather than a Ghostty-only component.
• –The tradeoff is that embedders inherit a substantial terminal-protocol surface, but centralized maintenance should reduce fragmentation and improve compatibility for everyone.
