Builds and runs the VST3 ABI test harness on macos-latest against Zig 0.14.1. Verified green from a clean checkout of main. macOS only for now: the webui example imports CoreAudio, so a Linux job would need that path excluded first.

setup-zig@v1 builds the pre-rename artifact filename, which no longer
exists. Zig swapped arch and OS in its release names, so v1 requests a
path that 404s on every mirror and on ziglang.org itself:
zig-linux-x86_64-0.14.1.tar.xz 404 <- requested by v1
zig-x86_64-linux-0.14.1.tar.xz 200 <- actual
The run failed at step 3 with "Unexpected HTTP response: 404" after
exhausting all five mirrors, then failed again in post-cleanup with
"Unable to locate executable file: zig".
v2 knows the current naming.

Zig 0.14.1 does not locate libSystem on the macos-latest runner on its
own, so linking fails before any danzig code is reached — the build
runner itself cannot link:
error: undefined symbol: _malloc_size
error: undefined symbol: _realpath$DARWIN_EXTSN
note: referenced by .../build.o:_posix.abort
Exporting SDKROOT from xcrun gives it the path. danzig has to stay on
macOS: the GUI example links CoreAudio and CoreFoundation, and the VST3
bundle is a macOS artifact.

macos-latest now ships Xcode 26.5, whose SDK Zig 0.14.1 cannot link
against. Every libc symbol comes out undefined, and it fails before
reaching any danzig code — the build runner itself will not link:
error: undefined symbol: _malloc_size
note: referenced by .../build.o:_posix.abort
Setting SDKROOT from xcrun did not help, because the SDK is the problem
rather than its discoverability. macos-15 ships an SDK from before
Zig 0.14.1's release.
danzig has to stay on macOS: the GUI example links CoreAudio and
CoreFoundation, and the VST3 bundle is a macOS artifact. Replaces the
SDKROOT step with a toolchain report, so the next SDK break is obvious
from the log.
