+-- COMMON PLUGINS - Loaded for all filetypes/profiles
+-- ========================================================================
+--
+-- This file contains plugins that are always loaded regardless of what
+-- file type you're working with. These are your "core" plugins that
+-- provide functionality across all your language profiles.
+--
+-- Examples: file explorers, git tools, common UI elements, copilot, etc.

+  -- FILE EXPLORER - Neo-tree
+  -- ========================================================================
+  -- Neo-tree provides a modern file explorer sidebar similar to VS Code.
+  -- It's loaded for all profiles so you can browse files regardless of
+  -- what language you're working with.
+  --
+  -- Keybindings:
+  --   \ (backslash) - Toggle Neo-tree file explorer
+  --   Within Neo-tree:
+  --     a - Add file/folder
+  --     d - Delete
+  --     r - Rename
+  --     x - Cut
+  --     c - Copy
+  --     p - Paste
+  --     ? - Show help (see all keybindings)
+  --
+  -- Note: This references the existing neo-tree configuration from
+  -- kickstart/plugins/neo-tree.lua. We're just ensuring it's loaded.

+  -- GITHUB COPILOT - AI pair programming assistant
+  -- ========================================================================
+  -- GitHub Copilot provides AI-powered code completions and suggestions.
+  -- Works across all file types and integrates with your completion engine.
+  --
+  -- Setup:
+  --   1. After installing, run :Copilot setup
+  --   2. Follow the authentication flow
+  --   3. You'll need an active GitHub Copilot subscription
+  --
+  -- Usage:
+  --   - Copilot suggestions appear automatically as you type
+  --   - Press Tab to accept a suggestion
+  --   - Press Ctrl+] to see next suggestion
+  --   - Press Ctrl+[ to see previous suggestion
+  --   - :Copilot panel - Open completion panel with multiple suggestions
+  --
+  -- Commands:
+  --   :Copilot setup   - Authenticate with GitHub
+  --   :Copilot status  - Check authentication status
+  --   :Copilot enable  - Enable Copilot
+  --   :Copilot disable - Disable Copilot
+  -- ========================================================================

+    'github/copilot.vim',
+    lazy = false, -- Load immediately on startup (not lazy-loaded)
+    config = function()
+      -- Copilot keybindings (optional customization)
+      -- By default, Tab accepts suggestions, but this might conflict with completion
+      -- Uncomment below to use Ctrl+J to accept instead:
+      -- vim.keymap.set('i', '<C-J>', 'copilot#Accept("\\<CR>")', {
+      --   expr = true,
+      --   replace_keycodes = false,
+      -- })
+      -- vim.g.copilot_no_tab_map = true
+
+      -- Optional: Disable Copilot for certain filetypes
+      -- vim.g.copilot_filetypes = {
+      --   ['*'] = true,
+      --   ['markdown'] = false,
+      --   ['text'] = false,
+      -- }
+    end,
+  },

+  -- ========================================================================
+  -- ADDITIONAL COMMON PLUGINS
+  -- ========================================================================
+  -- You can add more common plugins here that should be available across
+  -- all language profiles. Examples:
+  --
+  -- - Better terminal integration
+  -- - Git integration enhancements (beyond gitsigns in init.lua)
+  -- - Session management
+  -- - Project management
+  -- - Alternative completion sources
+  -- - UI enhancements
+  --
+  -- Just add them to this return table following the same pattern as above.
