[BUG] floating window does not disappear when diff view is shown

issue では ClaudeCodeFocus と diff-view フローについて言及されています。terminal.snacks_win_opts.position を float に設定し、diff_opts.keep_terminal_focus=false にして再現してください。ClaudeCodeFocus と diff のオープン処理周辺のフォーカスおよびウィンドウ処理を追跡し、その後、diff を開くと 2 回目のフォーカス呼び出しなしでフローティングウィンドウが非表示になることを確認してください。

Bug Description

With terminal.snacks_win_opts.position is set to float, the floating window does not disappear when a diff view is opened. Instead, the diff view is visible and has cursor focus. Calling ClaudeCodeFocus will switch focus to the open floating window. Calling it again will make the window disappear and switch to the diff view. However, this is a very cumbersome workaround.

My config:

{
  terminal_cmd = "~/.claude/local/claude",
  diff_opts = {
    keep_terminal_focus = false,
  },
  terminal = {
    snacks_win_opts = {
      position="float",
      width=0.9,
      height=0.9,
      backdrop={
        bg="blue",
        blend=90,
      },
      keys = {
        claude_hide = {
          toggle_key,
          function(self)
            self:hide()
          end,
          mode="t",
          desc="Hide",
        }
      },
    }
  }
}

To Reproduce

Steps to reproduce the behavior:

1. Open a file and launch Claude Code by calling ClaudeCodeFocus.
2. Ask Claude to produce a change to the code.
3. Observe that the diff view opens, with the cursor on it, but the floating window is still visible mostly obscuring it.

Expected Behavior

The floating window should disappear when the diff view opens.
