This fixes the VS16 issues found in this test:
https://ucs-detect.readthedocs.io/sw_results/ghostty.html#ghostty
This is also a more robust way to handle VS15/16 in general.
This commit also changes our propeties to be a packed struct which
reduces its size from 4 bytes to 1 and likewise drops our unicode table
size 4x.
This updates uucode. As part of this, the wcwidth implementation was
updated (in uucode) to make emoji modifiers width ZERO. But if they're
standalone, we want them as width 2.
So this also contains a change to force them as width 2 for our width
calculation. This only matters for standalone emoji modifiers, because
when they form a valid grapheme we don't use this width calculation.
- update nixpkgs now that Zig 0.15.2 is available in nixpkgs
- drop hack that worked around compile failures on systems with more
than 32 cores
- enforce patch version of Zig
Update libvaxis. The latest commit of libvaxis includes `uucode` as the
unicode
library. `uucode` has a much cleaner API and is actively developed by a
Ghostty
maintainer (@jacobsandlund). This also has the advantage of removing the
last
transitive dependency Ghostty has that is hosted on codeberg, which
separates us
from the frequent outages.

Release notes at:
https://github.com/vancluever/z2d/blob/v0.9.0/CHANGELOG.md
This release brings our Zig 0.15.x branch into main, now that Ghostty is
on it too.
Additionally, this adds major speedups to the default path (filling with a
solid color using the default operator).
This adds a new script we can manually run that downloads all the files
that need to be uploaded to the mirror and updates our build.zig.zon.
The upload still happens manually [by me] but this simplifies the task
greatly.
Since we now use uucode, we don't need ziglyph anymore. Ziglyph was kept
around as a test-only dep so we can verify matching but this is
complicating our Zig 0.15 upgrade because ziglyph doesn't support Zig
0.15. Let's just drop it.
This makes more dependencies lazy. This has a practical effect of
reducing the number of dependencies that need to be downloaded when
running certain zig build steps.
This is all limited because we're blocked on an upstream Zig issue:
https://github.com/ziglang/zig/issues/21525 This prevents us from fully
avoiding downloading many dependencies, but at least they're relatively
small.
One major improvement here is the usage of `lazyImport` for
`zig-wayland` that prevents downloading `zig_wayland` unconditionally on
all platforms. On macOS, we don't download this at all anymore.
Another, weirder change is that all our transitive dependencies are now
marked lazy (e.g. glslang's upstream source) even if the glslang build
always requires it. This was necessary because without this, even if we
simply referenced glslang in the root build.zig, it would force the
source package to download unconditionally. This no longer happens.
cc @pluiedev Minor improvements here, doesn't change the long term plan,
but improves things in the interim.
