## Summary

Implemented useful Copilot follow-ups: direct toErrorDetails test coverage and improved flush reliability for background-task and ChannelDO logging paths.

**Approach:** Standard approach

---

## Key Decisions

### Added explicit tests for toErrorDetails helper edge cases
- **Chose:** Added explicit tests for toErrorDetails helper edge cases
- **Reasoning:** Covers Error with stack, Error without stack, and non-Error values to prevent regressions in structured error metadata.

### Added flush calls in background error handler and ChannelDO fetch finally block
- **Chose:** Added flush calls in background error handler and ChannelDO fetch finally block
- **Reasoning:** Improves delivery reliability for async log exports in contexts without request middleware lifecycle hooks.
