Elyra Conductor v0.7.8

Changed

• Much snappier terminals. PTY output now streams to the UI over a binary
  channel instead of JSON events. Previously every byte was serialized into a JSON
  array (~3.6× larger) and re-parsed on the UI thread for every frame — which made
  repaint-heavy TUIs like the Elyra agent feel sluggish next to a native terminal.
  Output is now shipped as raw bytes (zero-copy), cutting per-frame decode work on
  the UI thread by ~100×. Typing and rendering no longer compete with JSON parsing.
