Perf

[khezen]

Changed

• Parallelized scope processing in code reviewer, doc reviewer, and supply chain auditor using asyncio.gather — multi-scope PRs now review scopes concurrently instead of sequentially
• Reduced default_max_iters from 4 to 3
• Reduced default_max_llm_calls from 8 to 5
• Reduced llm_retries from 3 to 2
• Scope resolver max_iters changed from 20 to null (inherits default_max_iters: 3)
• Code review reasoning_effort default changed from high to medium in .env.example
• Auditor episode save switched from background fire-and-forget to synchronous (auditor is the last pipeline module)

Added

• join_episode_saves() call at end of review pipeline to ensure all background episode saves complete before returning results

Removed

• docker-run-json Makefile target
