Configure lua_ls LSP settings for Neovim Lua development

[user3301]

Problem

lua_ls is registered in lsp.lua but has no settings configured. This causes false undefined-global warnings for vim and LazyVim globals in Neovim config files.

Solution

Add proper lua_ls settings to nvim/.config/nvim/lua/plugins/lsp.lua:

lua_ls = {
  mason = not is_nixos,
  settings = {
    Lua = {
      runtime = { version = "LuaJIT" },
      workspace = {
        checkThirdParty = false,
        library = vim.api.nvim_get_runtime_file("", true),
      },
      diagnostics = {
        globals = { "vim", "LazyVim" },
      },
      telemetry = { enable = false },
    },
  },
},

Expected Result

• No more undefined-global warnings for vim and LazyVim
• Proper Neovim API completions and type checking in Lua config files
