bug: close_if_last_window bypasses "E37: No write since last change" on quit attempt

[Minitajfun]

Did you read the documentation and check existing issues?

• I have read all the :help neominimap documentation
• I have updated the plugin to the latest version before submitting this issue
• I have searched the existing issues and closed issues issues

Neovim version (nvim -v)

0.11.6

Operating system/version

Arch Linux

Describe the bug

When the 'layout' is set to 'split' and 'close_if_last_window' to true, as long as the minimap is enabled closing the last file while there are unwritten changes does not yield the expected E37: No write since last change.

Instead, the program is outright quit, and the changes to the files are lost.

Steps To Reproduce

1. Install the plugin
2. Set 'layout' to 'split' and 'close_if_last_window' to 'true' in the config
3. Open any file(s)
4. Make sure minimap is enabled
5. Edit any file(s)
6. Close the file(s) without writing the changes
7. NeoVim now exits without showing E37

Expected Behavior

E37: No write since last change should be displayed when trying to quit NeoVim with unwritten changes.

This happens because nvim by default hides modified buffer on :q, so :bn can still work without error, it's not closed completely. But with close_if_last_window=true neominimap forcibly closes all unsaved hidden buffers.

This may lead to data loss:

neominimap.nvim/lua/neominimap/window/split/internal.lua

Lines 189 to 191 in 0676085

	if not ok then
	vim.cmd("noau qa!")
	end

Solution is to use layout = "float" in vim.g.neominimap. Float mode doesn't have this issue because it doesn't count as a real window.
