Event field type for keyboard key names.

Parses wire-format key name strings (PascalCase, e.g. "ArrowRight", "Escape") into Elixir atoms (:arrow_right, :escape). Single character keys pass through as strings ("a", "1").

Delegates to Plushie.Protocol.Keys.parse_key/1 for the actual mapping.

Examples

iex> Plushie.Type.Key.parse("Escape")
{:ok, :escape}

iex> Plushie.Type.Key.parse("a")
{:ok, "a"}

iex> Plushie.Type.Key.parse(nil)
:error
