test(output_format_contract): add plugins json coverage to inventory_commands test

Add four assertions to inventory_commands_emit_structured_json_when_requested:
- kind == "plugin"
- action == "list"
- reload_runtime is boolean
- target is null when no plugin is targeted

Closes the only major --output-format json surface with zero contract
coverage. All other surfaces (agents, mcp, skills, status, sandbox,
doctor, help, version, acp, bootstrap-plan, system-prompt, init, diff,
config) already had test assertions.
