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.

Fixes#8406
Spatial split navigation now wraps at the edges.
We first attempt the nearest spatial target using the existing slot geometry.
If there is no candidate in the requested direction, we synthesize a wrapped
target by shifting the current slot by one full grid in the opposite
direction and reuse the same nearest-distance logic.
This fake target works because the grid is 1x1, so by moving it a full
grid size in the opposite direction, we effectively wrap around to the
other side of the grid.
When a tab contains only a single split, resize_split and toggle_split_zoom
actions now return false (not performed). This allows keybindings marked with
`performable: true` to pass the event through to the terminal program.
The performable flag causes unperformed actions to be treated as if the
binding didn't exist, so the key event is sent to the terminal instead of
being consumed.
- Add isSplit() helper to SplitTree to detect single-pane vs split state
- Update GTK resizeSplit/toggleSplitZoom to return false when single pane
- Update macOS resizeSplit/toggleSplitZoom to return Bool and check isSplit
- Add unit test for isSplit method
As of Zig 0.14.0, `@splat` can be used for array types, which eliminates
a lot of redundant syntax and makes things generally cleaner.
I've explicitly avoided applying this change in the renderer files for
now since it would just create rebasing conflicts in my renderer rework
branch which I'll be PR-ing pretty soon.
