/**
 * Cross-platform abort for spawned `docker` / `docker buildx` processes.
 *
 * `child_process.spawn(...).kill('SIGTERM')` on Windows translates to
 * `TerminateProcess` — equivalent to SIGKILL, with no grace window. We
 * use `taskkill /T /F /PID` instead so child trees (`docker` → buildkitd)
 * are torn down explicitly. POSIX gets the standard SIGTERM-then-SIGKILL
 * grace pattern.
 *
 * `platform` is injected so tests pass `"win32"` directly without
 * `vi.stubGlobal('process', ...)`, which is fragile and leaks across
 * tests.
 *
 * Stream cleanup before signalling per robustness-standards § "Process
 * Timeout with Stream Cleanup".
