YeonGyu-Kim bff370003b fix: plugins extra-arg errors now return non-null hint via newline-delimited usage string
Parity with #791 (config extra-arg fix). The plugins arg parser emitted
'unexpected extra arguments after claw plugins show ...' with no newline
delimiter, so split_error_hint returned None. Added usage hint after newline.
60 CLI contract tests pass.
