/**
 * Run `tar <args...>` in a cross-platform way.
 *
 * Args MUST be `["-czf", outPath, "-C", stageDir, "."]` style (no
 * shell quoting needed because we use execFileSync, not execSync).
 *
 * After the Critical #3 fix:
 *   - Honors PEAKS_TAR_BIN / TAR env vars.
 *   - On Windows, tries C:\Windows\System32\tar.exe first; falls back
 *     to PATH lookup if it's missing.
 *   - Accumulates tar's stderr and re-throws it on non-zero exit so
 *     operators can see WHY tar failed (path typo, permission, corrupt
 *     stage dir, etc.) instead of swallowing it.
 *
 * Throws `TAR_NOT_FOUND` when the binary cannot be located.
