## Problem
Users who want keybindings must call Lua functions directly or wrap
commands in closures. There is no stable public API for key binding.
## Solution
Define <Plug> mappings in the plugin file and document them in a new
MAPPINGS section in the vimdoc.
- Update homepage URL to barrettruth.com
- Replace setup() docs with vim.g.live_server config
- Add luarocks installation to readme
- Remove lazy.nvim specific example
