Mitchell Hashimoto 3fc04fd4ae build: replace lib-vt step with -Demit-lib-vt option

Remove the dedicated `zig build lib-vt` step and replace it with a
`-Demit-lib-vt` build option. This fixes two problems:

1. We can default XCFramework, app, etc. steps to false if emit-lib-vt
   is true, so that the lib-vt build doesn't pull in unrelated
   artifacts. **Most importantly, lib-vt alone can be build without
   full Xcode installations.**

2. We can build lib-vt as part of a bundle with other artifacts if we
   really want.

WebAssembly Key Encoder Example

This example demonstrates how to use the Ghostty VT library from WebAssembly to encode key events into terminal escape sequences.

Building

First, build the WebAssembly module:

zig build -Demit-lib-vt -Dtarget=wasm32-freestanding -Doptimize=ReleaseSmall

This will create zig-out/bin/ghostty-vt.wasm.

Running

Important: You must serve this via HTTP, not open it as a file directly. Browsers block loading WASM files from file:// URLs.

From the root of the ghostty repository, serve with a local HTTP server:

# Using Python (recommended)
python3 -m http.server 8000

# Or using Node.js
npx serve .

# Or using PHP
php -S localhost:8000

Then open your browser to:

http://localhost:8000/example/wasm-key-encode/

Focus the text input field and press any key combination to see the encoded output.
