Bug: reminder request creates skill instead of task

Current behavior

• When the user asks the agent to create a reminder, the agent calls create_skill and creates a skill instead of a reminder task.

Expected behavior

• Reminder requests should call create_task to create a scheduled reminder task (not a skill).

Repro

1. In chat, ask the agent: "create a reminder for me ..."
2. Agent creates a skill (via create_skill) instead of a scheduled task.

Impact

• Reminders fail (no task scheduled).
• Skill spam / incorrect artifacts in the system.

Suggested fix

• Add tool routing guardrails: reminder intent must map to create_task (scheduled) and must never call create_skill.
• Add/ensure a unit/regression test that covers this.
• Apply the existing internal note/skill: '(oops) create CORE scheduled reminder tasks, not skills' (d4522a13-5f0f-4532-adf1-70a5f9cbe0fe) so it triggers on reminder requests.

Acceptance criteria

• Any reminder request always creates a scheduled task via create_task.
• No skills are created for reminder requests.
• Regression test added to prevent this from recurring.
