Port of the data race fix from Ox project (softwaremill/ox#346). The original implementation used separate channels for child outputs and completion signals, which could lead to race conditions. This change unifies them into a single channel using a sealed interface hierarchy, eliminating the race condition. Changes: - Replace separate childOutput and childDone channels with unified ChildOutput channel - Introduce ChildOutput sealed interface with ChildValue and ChildDone implementations - Update channel selection logic to handle unified output channel - Add stress test to validate the fix (100k iterations) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
