fix: Several small updates.

- Removing the load_lauunchjs call for dap as it's no longer needed.
- Cleanup of lspconfig of several lines that appear to not do anything
  in testing, and updating keymap order.
- Removing the luasnip setup section as it appears to not be required in
  testing.
- Update to nvim-cmp for luasnip relative loading and removing the
  buffer from command mode completion
- Twilight update to narrow the focus but also expand out if statements.
- ZSH re-enabling keychain despite it being slow as replacement with
  gpg-agent will take a focused session to do across environments
