1.14.1

fixed

• Fixed chat failing with 400 The legacy Interactions API schema is no longer supported.
  - Upgraded @google/genai SDK from 1.46 to 2.8 to adopt the new "steps" schema
  (the legacy "outputs" schema was removed by Google on June 8, 2026).
  - Streaming now uses the new SSE event types (interaction.created, step.start,
  step.delta, step.stop, interaction.completed).
  - Function call arguments are accumulated from arguments_delta events and
  finalized on step.stop, matching the new streaming protocol.
  - Function results are now sent back as Step[] (function_result + user_input)
  instead of the previous Content[] shape.
  - Annotation sources are read from the new text_annotation_delta events,
  supporting URLCitation, FileCitation, and PlaceCitation shapes.
  - Deep Research now reads result.output_text / result.steps instead of the
  removed result.outputs field.
