fix(anr): Align stack collection limit with queue capacity and avoid closing caller-owned stream

cursoragent · cursoragent · commit 408aaa27a174 · 2026-03-06T07:30:58.000Z
- Changed MAX_NUM_STACKS to match queue capacity (120 instead of 151) to prevent stack eviction
- Removed try-with-resources in toStream to avoid closing the caller-owned OutputStream
