fix: remove non-functional WebSocket integration and final type fixes

- Remove chanx-based WebSocket integration (API not available/stable)
- Replace WebSocket modules with TODO placeholders for future implementation
- Fix remaining mypy type errors (Dict usage, enum serialization, datetime handling)
- Resolve circular import in branch.py by removing Pipeline dependency
- All 62 tests pass, mypy clean, ruff compliant

WebSocket integration will be implemented in a future version with a stable library.
