[BUG] Somehow my UI for the diff preview is glitches

[edwardtran1561]

Bug Description

When claude code ask me to edit a file, the preview ui in my neovim somehow is glitch.

To Reproduce

Steps to reproduce the behavior:

1. cd to a work directory, then run nvim
2. open a file, ac to open claude code pane
3. Tell claude code to edit something

Expected Behavior

The split pane of preview diff should show the right position

Environment

• Neovim version: 0.11.6
• Claude Code CLI version: 2.1.84
• OS: MacOS Tahoe 26.3.1
• Plugin version: Latest

Additional findings

The bug only occurs when using Snacks Explorer (LazyVim default).
Switching to neo-tree resolves the issue completely.

This suggests claudecode.nvim does not properly detect snacks_explorer
window type when deciding where to open the diff split.

Expected: diff should open in the editor window, not the explorer window

	opts = {

			open_in_new_tab = true,
		},
	},
	keys = {
		{ "<leader>a", "", desc = "+ai", mode = { "n", "v" } },
		{ "<leader>ac", "<cmd>ClaudeCode<cr>", desc = "Toggle Claude" },
		{ "<leader>af", "<cmd>ClaudeCodeFocus<cr>", desc = "Focus Claude" },
		{ "<leader>ar", "<cmd>ClaudeCode --resume<cr>", desc = "Resume Claude" },

		{ "<leader>ab", "<cmd>ClaudeCodeAdd %<cr>", desc = "Add current buffer" },
		{ "<leader>as", "<cmd>ClaudeCodeSend<cr>", mode = "v", desc = "Send to Claude" },
		{
