* 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.

* test(sqlness): run environments concurrently with external backends
The runner forced both environment and instance parallelism to 1 whenever
etcd/PG/MySQL or an external Kafka was set up, so the standalone and
distributed environments ran one after the other.
Only distributed uses the kv backend, and the two environments use
different Kafka topic prefixes, so they can run at the same time. Keep one
instance per environment, since instances would share the metadata table
and Kafka topics. Runs with a runner-managed Kafka, an external server, a
test filter, or `-j 1` stay fully serial.

* test(sqlness): drop redundant restarts and sleeps
- flow_rebuild: drop the R2 block, which repeats R1 from the same state,
and the restart in R5, whose result R1 already asserts.
- flow_advance_ttl, flow_view, ttl_instant: drop sleeps that no assertion
depends on.
- flow_basic, flow_null, flow_call_df_func: drop the bytes_log section
(covered by flow_insert), a duplicate state_size query, an unchecked
insert, and flushes that run with no new data.
- alter_table_options, skip_wal: share restarts between independent tables.
- session_skip_wal, copy_skip_wal: check every case after a single restart.
Tables copied or inserted with skip_wal = true first get a WAL row that is
truncated, so the check that truncated WAL entries are not replayed stays.
- region_statistics: wait once for the statistics of all three tables.
- build_index_table: fold its index_size checks into
build_index_table_restart, which runs the same fixture and waits.

* test(sqlness): restore session_skip_wal and copy_skip_wal
Checking every case after a single restart dropped two state transitions
the original cases cover: recovering a region whose memtable only held
skipped rows, and writing to the recovered region before restarting again.
Restore the original cases.

* test(sqlness): restore the one-restart check in flow_auto_sink_table
#5112 checked the auto-created sink before a restart and the flow and sink
after it. #5987 moved the restart in front of the first SHOW and added a
second one. Flow recovery only creates the sink when it is missing, so the
second restart recovers from the same persisted state as the first.
Restore the original before/after check with one restart.

* test(sqlness): keep one instance per environment with external store addresses
Instances of the distributed environment share the etcd behind --store-addrs, so run one instance per environment when it is set, same as --setup-etcd.

* test(sqlness): restore the false-branch batch in flow_basic and assert it
The kept batch (20, 22) is all above the threshold. The second batch (10, 23) is the only input that hits the false branch of the CASE and makes the flow compute again. Restore it and check the result, which the original case never did.
