Move the draft-annotation logic (PaddleOCR line detection, word-box
grouping, three script-chosen recognition engines, crop-jitter
stability gate) from the evaluation-only scripts into the installable
package, with lazy paddle imports and a text-draft extra (CPU, no
torch). draft_text_lines() returns accepted (crop-stable, NEVER
ground-truth-correct - precision on the reference posters was 90.0% /
94.4%) and rejected proposals; source_pixel_sha256 is re-exported for
manifest building. scripts/infer_text_lines.py now dogfoods the
package module instead of loading the eval script by path.
