fix(ci): download rusty_v8 override artifacts for all release targets

The setup-rusty-v8 step was gated on `contains(matrix.target,
'unknown-linux-musl')` in build-unix and missing entirely from
build-windows. After the v8 crate bumped 149.2.0 -> 150.4.0, the v8
build.rs default downloader requests `librusty_v8_ptrcomp_sandbox_release_*.a.gz`
from denoland/rusty_v8, which never published that profile name, so the
non-musl targets (macOS x86_64/aarch64, Windows x86_64) failed with 404.

Remove the musl-only guard in build-unix and add the same step to
build-windows so every target downloads the Codex-built
`ptrcomp_sandbox_release` override artifacts from
openai/codex rusty-v8-v150.4.0, matching upstream 0.148's unconditional
setup-rusty-v8 invocation.
