Closing the quickfix window previously triggered a WinClosed autocmd
that deleted all difftool autocmds and pushed an empty quickfix list,
making the difftool non-functional. Users who close the quickfix window
to gain screen real estate for viewing diffs had no way to continue
navigating entries.
Remove the qf_win tracking and its associated WinClosed autocmd so that
closing the quickfix window no longer tears down the difftool state.
Closing either diff window still performs full cleanup as before.
The BufWinEnter handler no longer passes with_qf to diff_files, so
navigating entries while the quickfix window is closed reuses the
existing diff layout without forcing a layout rebuild.
Fixes#37388
Fixes issue on mac where it was constantly reloading buffers as paths
were not being normalized and resolved correctly (in relation to buffer
name).
Quickfix entry:
/var/folders/pt/2s7dzyw12v36tsslrghfgpkr0000gn/T/git-difftool.m95lj8/right/app.vue
Buffer name:
/private/var/folders/pt/2s7dzyw12v36tsslrghfgpkr0000gn/T/git-difftool.m95lj8/right/app.vue
/var was synlinked to /private/var and this was not being properly
handled.
Also added lazy redraw to avoid too many redraws when this happens in
future and added test for symlink handling.

- Always open the right window to the right, regardless of 'splitright'
setting, ensuring the left window is always leftmost.
- Use `vim.fn.systemlist` for diffr output to avoid manual splitting.
- Add a test to verify window layout consistency with 'splitright' and
'nosplitright' options.
- Escape quotes in git difftool example properly.

Problem:
Built-in diff mode (nvim -d) does not support directory diffing
as required by git difftool -d. This makes it difficult to compare
entire directories, detect renames, and navigate changes efficiently.
Solution:
Add a DiffTool plugin and command that enables side-by-side diffing of
files and directories in Neovim. The plugin supports rename detection,
highlights changes in the quickfix list, and provides a user command for
easy invocation. This allows proper integration with git difftool -d for
directory comparison.
Example git config:
```ini
[diff]
tool = nvim_difftool
[difftool "nvim_difftool"]
cmd = nvim -c "packadd nvim.difftool" -c "DiffTool $LOCAL $REMOTE"
```
