v0.4.0

Changed

• BREAKING: Streaming event data now decoded with string keys
  • Claudio.Messages.Stream.parse_events/1 previously decoded SSE event payloads with Poison.decode(keys: :atoms), producing atom-keyed data maps. It now decodes with Poison's default (string keys), matching the raw Anthropic JSON convention.
  • This is a breaking change for external consumers that pattern-match on atom keys inside event.data (e.g. %{delta: %{type: "text_delta"}}). Downstream code should switch to string keys (%{"delta" => %{"type" => "text_delta"}}).
  • Claudio's internal helpers (accumulate_text/1, apply_delta/2, build_final_message/1, update_current_block/2) already read data["x"] || data[:x] defensively, so this is a no-op inside Claudio.

Fixed

• Fail loudly on malformed SSE JSON payloads
  • parse_event/1 previously swallowed Poison.decode/1 errors as {:ok, %{event: ..., data: nil}}, hiding corruption and leaving downstream consumers to operate on silently-missing data.
  • Decode failures now return {:error, {:invalid_event_data_json, event_type, reason}}, consistent with the existing {:invalid_event, _} error tag emitted by the same function.
