Bug Description

openclaw cron add CLI command fails with validation error.

Environment

• openclaw: linux/amd64
• node: v22.22.1
• npm global: ~/.npm-global

Steps to Reproduce

openclaw cron add --name test --every 300 --message ping

Expected

Cron job should be created successfully.

Actual

Validation failed for tool "cron": - job: must be object

Root Cause

CLI sends flat arguments:

{ "action": "add", "name": "test", "every": 300, "message": "ping" }

But cron tool schema expects a job wrapper:

{ "action": "add", "job": { "name": "test", "schedule": {...}, "payload": {...} }}

Impact

• All cron jobs fail to create via CLI
• TangSeng workflow automation cannot be set up
• Every 5-minute task polling is broken

Suggested Fix

CLI should wrap the job payload in a job field before calling the cron tool.
