cli+lsp: refactor main packages into internal runners; add tests

- Move CLI logic to internal/hexaicli with Run/RunWithClient
- Move LSP logic to internal/hexailsp with Run/RunWithFactory
- Extract helpers; keep behavior identical for both binaries
- Add unit tests for hexaicli (input parsing, messages, streaming) and
  hexailsp (factory wiring, client creation, logging settings)
- Add top-of-file summaries and 'Not yet reviewed by a human' comments to all Go files
- Update README with internal package docs
