/**
 * The bounded wait every runtime-validation command runs under.

 * Stated ONCE and exported so no call site writes its own number: a bound
 * hard-coded per caller is how two callers end up disagreeing about how long
 * "too long" is, and the drain's progress guarantee then depends on which one
 * you happened to read. Generous, because a validation command is host-authored
 * and may legitimately be a whole suite — what matters is that it is FINITE.

/**
 * Terminate a timed-out child, INCLUDING anything it spawned.
 *
 * On win32 this runner wraps package-manager shims in `cmd.exe /d /s /c` (see
 * `resolveRuntimeValidationSpawnCommand`), so the process we hold a handle to is
 * the shell, not the tool: `child.kill()` reaps the wrapper and leaves the npm →
 * node grandchildren running, which is the orphan case the bound exists to
 * prevent. `taskkill /T` walks the tree instead. Everywhere else the executable
 * is spawned DIRECTLY — no wrapper, so no tree of our making — and the signal
 * pair is the whole story. A command that itself forks a daemon on POSIX is
 * beyond what this can promise without a process group, and is left stated
 * rather than silently assumed.
 *
 * `platform` is a parameter so both branches are reachable from a test on either
 * OS; the taskkill spawn failing (absent, denied) falls back to SIGKILL rather
 * than leaving the child alive.
