Add missing panels to View menu

[dinocosta]

Objective

Ensure that all existing panels have corresponding menu items in the "View" menu. I was onboarding a friend to Zed yesterday that was having a hard time figuring out how to interact with the Agent. Although he did open the "View" menu, I noticed that the Agent panel item was missing from there, making it hard for new users to discover it exists.

Solution

• Add both "Agent Panel" and "Git Panel" entries to the menu items for the "View" app menu.
• Update the action used for the "Terminal Panel" menu item from terminal_panel::ToggleFocus to terminal_panel::Toggle to ensure we display a shortcut for this menu item.
  • Another valid option would be to update the default keymap to use terminal_panel::ToggleFocus instead but that would probably break existing user's expectations that the default shortcut toggles the terminal panel, instead of toggling its focus.
• Introduce zed_actions::git_panel to be able to extract its ToggleFocus action, following the existing pattern.

Next Steps

It's worth noting that, even though there's now an "Agent Panel" item mapped to the assistant::ToggleFocus action, its default keybinding is not displayed (at least on macOS), because of the way it's defined as cmd-? . Using cmd-shift-/ instead doesn't work, so we'll likely have to update MacKeyboardMapper to allow mapping between shifted and unshifted keys equivalent, that is, when ? is detected, it is able to determine that, in the user's layout that is the result of shift-/.

Testing

Manually tested, screenshots can be seen in the "Showcase" section.
