Neovim version (nvim -v)

v0.12.2

Operating system/version

Archlinux

Describe the bug

The proxy option in wk.add() does not respect noremap, which causes conflicts when remapping <C-w>.

Steps To Reproduce

1. Inside require("which-key").add({})
   1. Add { "<C-w>", "<C-w>q", noremap = true }
   2. Add { "<leader>w", proxy = "<C-w>", noremap = true }
2. Run nvim
3. Type <leader>w
4. The current buffer closes

Expected Behavior

Because noremap is set, the proxy should directly send <C-w> to vim instead of going through the { "<C-w>", "<C-w>q", noremap = true } mapping
