* 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.

* feat: rebuild legacy fulltext bloom indexes and probe lower(col)
The manifest records the fulltext bloom version per column, so ADMIN
BUILD_INDEX now rebuilds SSTs whose bloom index predates the current
tokens, and ssts_index_meta shows the version.
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.
