Inconsistent Virtual Text Placement with Tabs

[Nimrod0901]

Hi,
I'm encountering an issue with llm.nvim where virtual text is not correctly aligned when lines start with a tab character. Specifically, virtual text intended to be aligned with the cursor position defaults to column 1 when the line begins with a tab, whereas it aligns correctly when the line starts with spaces.

I digged into the source code and found the col came from llm-ls, I'm not sure if it's a bug of llm.nvim.

I found that adjusting the virt_text_win_col to account for the actual width of the tabs (considering the tabstop setting) resolves this issue on my local setup.

If this solution aligns with the project's direction, I would be happy to contribute a fix. Please let me know if a PR is welcome.

Have you had any trouble with not showing more than one line (when the model responded with multiple, checked via mitmproxy)... I've been wondering if it has something to do with tabs.
