 * Guarded auto-run helper (P1): true when this module is the process entry.
 * argv[1] is resolved through symlinks (realpathSync) BEFORE comparing because
 * Node resolves the entry module's real path into import.meta.url while
 * argv[1] keeps the SYMLINKED invocation path (e.g. the bin reached via
 * zob-harness/packages/pi-subagents). The raw pathToFileURL comparison never
 * matched in that case, leaving the bin silent (exit 0, no output, even for
 * --version). The raw comparison is kept as a fallback (--preserve-symlinks
 * and unresolvable paths). Exported for unit tests.
