agent::Toggle does not toggle Agent panel visibility on first invocation

Reproduction steps

1. Open Zed with the Agent panel available.
2. Ensure the Agent panel is visible but not focused.
3. Invoke agent::Toggle.
4. Observe that the Agent panel is focused, but remains visible.
5. Invoke agent::Toggle again.
6. Observe that the Agent panel is now hidden.
7. For comparison, invoke outline_panel::Toggle when the Outline panel is visible but not focused. It immediately hides the panel on the first invocation.

Current vs. Expected behavior

Current behavior

agent::Toggle behaves like a combination of agent::ToggleFocus and a toggle:
• The first invocation focuses the Agent panel without hiding it.
• The second invocation hides the Agent panel.

This differs from other panel toggle actions such as outline_panel::Toggle, which immediately hide/show their respective panel on a single invocation.

Expected behavior

agent::Toggle should consistently toggle the visibility of the Agent panel:

• If the Agent panel is visible, the first invocation should hide it.
• If the Agent panel is hidden, the first invocation should show it.
• It should not focus the panel as an intermediate step.

Since agent::ToggleFocus already exists specifically for focusing the Agent panel, agent::Toggle should behave like the other Toggle actions and only control panel visibility.

If you are using WSL on Windows, what flavor of Linux are you using?

None

Start at the agent::Toggle action and compare its behavior with outline_panel::Toggle and the existing agent::ToggleFocus action. Reproduce the visible-but-unfocused Agent panel case, then verify that one invocation hides it, one invocation shows it again, and focusing remains the responsibility of agent::ToggleFocus.
