* fix: align fulltext bloom tokens with matches_term and use them for LIKE The bloom fulltext index stored tokens that did not follow matches_term's word boundaries (`_`, ASCII next to Han, Han substrings), so pruning dropped rows matches_term accepts. Tokens and query probes now share the character classes of matches_term, Han runs are indexed as bigrams, and LIKE patterns use the same probes. The bloom blob is written under a new key; blobs from older versions are no longer probed. Tantivy no longer serves matches_term.

Case-insensitive bloom indexes also store the tokens of the whole lowercased text for rows where it can differ (U+0130, U+212A, sigma), so matches_term(lower(col), ..) and lower(col) LIKE .. use the index.
