/**
 * Cross-platform subprocess helpers for the ported hula workflow scripts.
 *
 * The original `.sh` scripts shell out to `git`, `gh` and the `hula` CLI. These
 * helpers reproduce that with Node's `child_process.spawn` and **no shell**, so
 * argument quoting is not a cross-platform hazard (no cmd/PowerShell/bash
 * escaping differences) — a core goal of the Windows-support port.
 *
 * `git` and `gh` are native executables found on PATH on every platform.
 * `hula`, however, is an npm bin that resolves to `hula.cmd` on Windows, which
 * `spawn` cannot launch without a shell. We sidestep that entirely by invoking
 * the CLI through `process.execPath` (the current Node binary) + the CLI entry
 * file ({@link cliEntry}), which is exactly the module already running.
