  "message": "perf: parallelize `rw?` tactic\n\nUse `MetaM.parIterWithCancel` to try all candidate rewrites in parallel\nwhile preserving deterministic result ordering. When an rfl-closeable\nresult is found (and `stopAtRfl` is true), or the maximum number of\nresults is reached, remaining tasks are cancelled.\n\nThis removes the old sequential `takeListAux` implementation along with\nthe heartbeat-based early termination and `RewriteResultConfig` structure.\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\n\nCo-Authored-By: Claude \u003cnoreply@anthropic.com\u003e\n",
