📄 Description

Stacked on #439 (zig 0.15 upgrade).

Adds terminal rendering support using ghostty-vt:

StatelessTerminalRenderable - fast renderer for first few lines of output (renders in ~ms, for opencode bash previews)

The terminal output is renderd line by line instead of using character cells. This should make it pretty fast even for super long ANSI outputs if they don't use many colors. Each line will simply be a line of text in opentui.

Includes VTerm FFI bindings and registration in React, Solid, and Vue.

Here is how bash outputs looks like in opencode using these terminal renderables (only stateless for now):
