Subject: [PATCH] fix: ngram min_gram=1 indexes tokens that can never be
 matched

Flarum's search UI enforces a minimum query length of 3 characters
(MIN_SEARCH_LEN in Search.tsx), so 1- and 2-character ngram tokens
are indexed but can never be queried. Changed min_gram from 1 to 3
and updated max_ngram_diff accordingly.
