Summary by cubic

Introduces a new streaming chat turn pipeline (Simple Agent V2) and a deep-research scratchpad agent, and wires chat processing to the new runner. Adds Braintrust tracing controls and an eval CLI flag to disable log sending.

• New Features

  • New chat turn infra: OnyxRunner, Emitter, and unified_event_stream for thread-safe, blocking event iteration.
  • fast_chat_turn agent using LiteLLM; process_message now streams via fast_chat_turn and parses agent/reasoning events.
  • Deep-research scratchpad agent with tools (web_search, web_fetch, internal_search), compaction hooks, and a clarification gate.
  • Braintrust updates: configurable masking length (BRAINTRUST_MASKING_LENGTH), tracing processor setup, demo agent, and --no-send-logs flag (propagated through evals).

• Refactors

  • gather_stream parses unified packet objects and builds responses from streaming deltas.
  • Simplified LLM logging (no-op) and minor DR prompt/CSV cleanup.
  • Temporary change: chat session rename endpoint returns a static placeholder.
  • Eval models/providers accept no_send_logs; added quality classifier scaffold.
