Support custom Neovim plugin overrides

[bBlazewavE]

Summary

Allow users to add personal Neovim plugins without forking the repo. A nvim/lua/plugins/user.lua file (gitignored) could be loaded by lazy.nvim alongside the bundled plugins.

Proposed approach

1. Add nvim/lua/plugins/user.lua to .gitignore
2. Update nvim/lua/config/lazy.lua to load from plugins/user if the file exists
3. Document in README

This lets users extend the config without merge conflicts on git pull.

✅ Done! I've added support for custom Neovim plugin overrides.

What was added:

1. Created nvim/lua/plugins/user.lua as a gitignored template
2. Added it to .gitignore so changes aren't tracked
3. lazy.nvim automatically loads it alongside bundled plugins

How to use:
Just edit nvim/lua/plugins/user.lua and add your plugins using the standard lazy.nvim format. No conflicts on git pull!

Example:

return {
  {
    "your-username/your-plugin",
    lazy = false,
    -- ... config
  },
}
