This commit represents the majority of the work necessary to upgrade Ghostty to use Zig 0.16.0. Key parts: * In addition to its previous responsibilities, the global state now houses state for global I/O implementations and the process environment. It is now also utilized in the main application along with the C library. Where necessary, global state is isolated from key parts of the implementation (e.g., in libghostty subsystems), and it's expected that this list will grow. * We currently manage our own C translation layer where necessary. In these cases, cImport has been removed in favor of the new external translate-c package. Due to fixes that have needed be made to properly translate the dependencies that were swapped out, as mentioned, we have had to backport fixes from the current translate-c package (and the upstream Arocc dependency). We will host this ourselves until Zig 0.17.0 is released with these fixes. * Where necessary (only a small number of cases), some stdlib code from 0.15.2 (and even from 0.17.0) has been taken, adopted, and vendored in lib/compat.

Example: vtStream API for Parsing Terminal Streams
This example demonstrates how to use the vtStream API to parse and process
VT sequences. The vtStream API is ideal for read-only terminal applications
that need to parse terminal output without responding to queries, such as:
- Replay tooling
- CI log viewers
- PaaS builder output
- etc.
The stream processes VT escape sequences and updates terminal state, while ignoring sequences that require responses (like device status queries).
Requires the Zig version stated in the build.zig.zon file.
Usage
Run the program:
zig build run
The example will process various VT sequences including:
- Plain text output
- ANSI color codes
- Cursor positioning
- Line clearing
- Multiple line handling
And display the final terminal state after processing all sequences.
