[BUG]: Confusing UI: "/plan to preview" hint doesn't match /plan behavior

Bug Description

After certain actions, Claude Code prints a hint suggesting /plan can be used to preview the plan:

Updated plan
  ⎿  /plan to preview

However, running /plan does not show any plan — it only toggles plan mode:

❯ /plan
  ⎿  Enabled plan mode

The hint message implies /plan will preview the plan, but the command's only behavior is toggling plan mode on/off. Either the hint is wrong or /plan is missing the preview behavior.

Steps to Reproduce

1. Trigger an action that produces the Updated plan / ⎿ /plan to preview message.
2. Run /plan.
3. Observe that no plan is shown — only Enabled plan mode appears.

Expected Behavior

One of:

• /plan shows the current plan when invoked after the "Updated plan" hint, or
• The hint message is changed so it doesn't reference /plan as a preview command.

Actual Behavior

/plan only toggles plan mode. There is no way to preview the plan referenced by the hint.
