feat: extract config.py, refactor CLI to use event-driven engine, add deprecation shim

- config.py: extracted load_config(), find_workspace_config(),
  load_discussion_config() from cli.py; fixed Windows root detection
- cli.py: run_discussion() now creates DiscussionEngine + EventEmitter,
  subscribes to events with ANSI-color output (identical to before),
  delegates to engine.run()
- backends/custom/run.py: deprecation shim with DeprecationWarning,
  delegates to DiscussionEngine
- 16 new config tests, all 184 tests passing
