Installing claude-code globally on the Windows server-tests runner
exposed 12 pre-existing Windows-specific test failures that were
silently skipped before (rmdir EBUSY during cleanup, .CMD spawn
EINVAL via the SDK, plus the launch-regression test that asserts
claude is *not* on PATH).
The Linux e2e tests (model-catalog, live-preferences, models) are
the only ones that needed the binary to flip isAvailable() true;
none of those run on Windows. Skip the install on Windows so those
Windows compatibility gaps stay surfaced separately and don't block
the SDK upgrade.
