…es (sqlancer#24,25,26,27,29,30)

Seven self-contained oracles (default-on, --flag gated, feature-absence tolerated):
- sqlancer#24 SequenceFunnel          windowFunnel/sequenceCount/sequenceMatch/retention == Java truth
                              (tiny deterministic fixture, far-from-boundary timestamps)
- sqlancer#25 PartitionLifecycle      DETACH+ATTACH/DROP/REPLACE/MOVE PARTITION row-set invariants
                              (SYSTEM STOP MERGES pins topology)
- sqlancer#26 AlterModifyConsistency  data-preserving ALTER MODIFY COLUMN/CODEC/TTL/SETTING + MATERIALIZE
                              must not change the visible multiset (modulo pre-applied widen cast)
- sqlancer#27 TtlDeterminism          TTL DELETE survivors == non-expired bucket; far-from-now() date
                              buckets keep the result wall-clock-independent
- sqlancer#29 InsertDedup             identical block re-insert leaves count unchanged (insert_deduplicate
                              default-on); distinct block grows; optional async arm
- sqlancer#30 TokenBf                 hasToken/=/IN with tokenbf_v1 index == use_skip_indexes=0 scan
- sqlancer#30 VectorIndexRecall       vector_similarity HNSW top-1 == brute-force top-1 + top-k containment
                              (never exact set-equality for ANN)

Completes all 30 plan ideas across 5 waves: 29 new oracles + Int128/256/Decimal256 emission +
EET roundtrip identities. ALL_ORACLES now 76 tokens; mvn package green (3.9M jar). Probe-on-head
(dev-vm): tokenbf_v1/vector_similarity grammar, windowFunnel/retention signatures, TTL materialize.

- sqlancer#22 AggregateStateExpansion: AggregatingMergeTree arm used finalizeAggregation(sumMerge(s))
  which double-finalizes (Code 43 ILLEGAL_TYPE_OF_ARGUMENT); sumMerge(s)/uniqExactMerge(u)
  already return the finalized scalar. Verified on head: sumMerge=10, uniqExactMerge=3.
- ClickHouseProvider: pin allow_experimental_{variant,dynamic,json}_type +
  allow_experimental_vector_similarity_index per connection so the VariantSubcolumn (sqlancer#18) and
  VectorIndexRecall (sqlancer#30) fixtures CREATE reliably (the oracle-issued SET could land on a
  different pooled connection than the CREATE). All four settings confirmed to exist on head.

Probe (head 26.6.1.743) confirmed all other 27 new-oracle constructs work as written:
Int128/Int256/Decimal(P,S), geo fns, windowFunnel/sequenceCount/retention, lagInFrame,
WITH ROLLUP/GROUPING/TOTALS, LIMIT WITH TIES/BY, *EXCEPT/APPLY/COLUMNS, SEMI/ANTI/ANY,
CoalescingMergeTree, Set/Join/joinGet, remote(), tokenbf_v1, vector_similarity, TTL DELETE,
unhex/base64/IPv4/IPv6 roundtrips.
