refactor: move core config from after/plugin/ and cfg/ to lua/config/

after/plugin/ runs after ALL plugins with unpredictable ordering. Explicit
require() from init.lua after lazy.setup() is more predictable and standard.

- after/plugin/autocmds.lua → lua/config/autocmds.lua
- after/plugin/mappings.lua → lua/config/keymaps.lua
- cfg/options.lua → config/options.lua
- cfg/utils.lua → config/utils.lua

Creates a consistent lua/config/ namespace for all non-plugin configuration.
