Issue #1041: Guidance on performance degradation

[facontidavide]

Summary

• Adds a drafted response for issue Performance issues when exiting after prolonged operation #1041 explaining that the reported performance degradation is likely user-side
• Root cause analysis found no unbounded state accumulation in parallel nodes or the tick loop
• Guidance: haltTree() must be called before re-ticking; thread-per-execution without halting leaks RUNNING state

Test plan

• No code changes — response document only
• Review guidance accuracy against ParallelNode::halt() source

🤖 Generated with Claude Code

Poem

🐰 A tale of trees that run and halt,
No state leaks here—that's not our fault!
Call haltTree true, before you go,
And watch your parallel branches flow. 🌳✨
