fix(sisyphus-junior): disambiguate blocked delegation tool from allowed task management tools

When task_system is enabled, the prompt said 'task tool: BLOCKED' which LLMs interpreted as blocking task_create/task_update/task_list/task_get too. Now the constraints section explicitly separates 'task (agent delegation tool): BLOCKED' from 'task_create, task_update, ...: ALLOWED' so Junior no longer refuses to use task management tools.
