Cut the dead attic workers, and file what the audit left standing

attic/worker_ocr.py and attic/worker_parse.py are 224 lines imported by nothing
and named in no doc. The OCR stage was removed when narration moved to the
director beat. The two design notes in attic/ stay, they are history.

worker_vision._panel_size had one reference and it was the definition.

The audit's larger finding is filed rather than fixed: call_gemma4,
_extract_json and _strip_thought exist in both worker_vision and worker_script
and have already diverged. That matters because the JSON repair pass can
fabricate dialogue, so a fix would land in one copy and not the other. It is
caveats/audit-open.md#gemma-helpers-duplicated with its revisit trigger.

HANDOFF.md carries the rest: _wrap2 against textwrap, the duplicated ONNX
preprocessing, and worker_layers pointing at a legacy/ directory that was never
tracked in git.

Checked: ruff clean, worker_vision and worker_render self-checks pass.
