PhoenixSpec.ParamsExtractor (PhoenixSpec v0.1.1)

Extracts request body schemas from Phoenix controller actions.

Detects patterns like:

Pattern matching %{"key" => value} in function args
Ecto.Changeset.cast(struct, params, [:field1, :field2]) in controller or schema changeset
Wrapper key nesting (e.g. %{"post" => post_params} wraps fields under "post")
