vtabs: terminal with vertical tabs on libghostty-vt + GTK4

Uses libghostty-vt (the API Ghostty documents for external embedders) for the terminal core. Ghostty's other C API, ghostty.h, exposes a full terminal surface but only supports macOS and iOS platform tags, so it cannot be embedded on Linux. We supply the layers libghostty-vt deliberately leaves out: PTY and process management, a Cairo/Pango cell renderer, and a GTK4/libadwaita UI with a Zen-style vertical tab sidebar. Nix pins the whole toolchain (Zig 0.16 via zig-overlay, GTK 4.22, libadwaita) so no host setup is needed.
