Module spell 

Thai spell correction using edit distance and phonetic ranking.

SpellChecker finds words in the built-in dictionary that are close to a given input, ranked first by phonetic similarity (lk82 Soundex), then by edit distance, then by TNC corpus frequency.

use kham_core::spell::SpellChecker;

let checker = SpellChecker::builtin();
let suggestions = checker.suggestions("กาน", 5);
// All candidates are within edit distance 2
assert!(suggestions.iter().all(|s| s.edit_distance <= 2));
// Phonetically similar words appear first
if let Some(first) = suggestions.first() {
    assert!(first.soundex_match || first.edit_distance <= 1);
}
