HOTFIX: Fix critical import errors in published package

- Fixed CircularBuffer → CircularSerialBuffer import
- Fixed ClientCapabilities → ClientCapabilitiesInfo import
- Fixed ClientDebug → ClientDebugInfo import
- Fixed SerialManager → SerialConnectionManager import
- Bumped version to 2025.09.27.2

These import errors prevented the published package from starting.
All components now use their actual class names.
