docs(reflow): split understanding-the-output.md into reference + how-to

The old single doc mixed 'what Reflow produces' (reference material) with 'what to check on a specific document' (a reviewer's how-to). Split so each doc is for one user mode. - reference/supported-document-types.md — size limits, quality matrix by doc type, known limitations, what the output contains. Authoritative lookup. - how-to/interpret-the-output.md — the 4-minute reviewer scan, warning triage, decision tree for when to file a correction vs. rerun vs. accept. Also: - File size limit updated from 'over 40 pages' to the actual hard limit (50 pages, 100 MB) per the pipeline's PDF classifier (equalify-reflow src/services/pdf_classifier.py). - Cost estimate added (~\$0.08–0.10 per page for Haiku tier) based on the observed run during the reflow tutorial work.
