v0.3.0: Markdown-aware mode

Quote check now reads AI feedback the way MV2's audit of 50,742 published feedback quotes did. Bold and italics, curly quotes, spacing, punctuation at a quote's two ends and capitals are set aside, and a new 'Why not exact' column names which one made the difference. An ellipsis inside a quote is read as words left out ('Same words, some left out'), and a changed quote that shows bold or italics is labelled 'Changed words, marked'. That leaves 'Changed words' for unmarked changes, the ones a teacher should read first. On by default; untick it to get v0.2.0's verdicts exactly. The checking code is unchanged byte for byte since v0.1.0, and the new reading is a JavaScript port of feedback-quote-audit's explain.py, checked against it on 4,000 seeded synthetic cases with 0 mismatches (and the original checker's 4,160-case parity check re-run with 0 mismatches). English and Spanish (Spanish translated with AI). Offline: the page loads and sends nothing. By MV2 of Munim, Inc. Made with AI agents working in his name. Apache-2.0.
