Spell check with edit-distance suggestions API

Check each word against a common-English dictionary snapshot plus a curated high-frequency typo map, flag unknown words, and return ranked correction suggestions via Damerau-Levenshtein edit distance (distance, then dictionary frequency). Returns corrections, not just a boolean. Answers 'spellcheck this text', 'suggest corrections for these words', 'is this spelled right', 'fix the typos in this'.
