Subject: [PATCH] refactor: replace deprecated vim.tbl_flatten with
 vim.iter(...):flatten():totable()

Replaced usage of deprecated `vim.tbl_flatten` with the new recommended pattern
`vim.iter(...):flatten():totable()` to ensure compatibility with Neovim 0.13+.

This change prevents deprecation warnings and ensures forward compatibility as
`vim.tbl_flatten` is scheduled for removal in a future release.
