fix: improve aggregate channel switching for MapReduce operations
- Add mutex protection to prevent race conditions in nextLine()
- Implement synchronous channel put-back in turbo mode when possible
- Add timeout mechanism to prevent goroutine leaks
- Increase NextLinesCh buffer size to 1000 for better concurrency handling
- Document known limitation with turbo mode and high-concurrency MapReduce
These changes ensure TestDMap3 passes consistently without turbo mode.
With turbo mode, extreme concurrency (100+ files) may still have issues
due to the fundamental mismatch between turbo mode's speed and the
aggregate's channel rotation design. Workarounds are documented.
