Libghostty 1.0 brings a stable C ABI for terminals

Libghostty-vt 1.0 makes the terminal-emulation library's C ABI stable, with semantic-versioning commitments and CI checks intended to enforce compatibility.

The release also adds signed source and dependency tarballs, standard packaging metadata, and shared and static library builds for major platforms.

The project says libghostty-vt is already used across JetBrains IDEs, developer tools, terminal projects, and commercial products.
