Subject: [PATCH] fix: check type of vim.list/vim.dict before using as function

On Neovim 0.12+, vim.list and vim.dict are table/module values, not nil.
The previous 'or' fallback never triggered, causing:
  E5113: attempt to call upvalue 'list' (a table value)

Fix by checking type() == 'function' before assigning.

Fixes #141
