Any plugin subcommand invoked with an undeclared option — e.g. openclaw workspaces audit export --since 1 before we declared that flag — prints OpenClaw does not recognize option "--since" and exits 0. Scripts and CI cannot distinguish a usage error from success.

Expected: non-zero exit on unrecognized options / usage errors (commander's own default behavior).
Observed: exit 0 on 2026.6.1.
