0.12.0-rc.1 PostgreSQL 17/18/19(beta1) EXPLAIN compatibility + HypoPG fix. - fix(pgexplain): support PG18 fractional Actual Rows (uint64->float64) and signed Query Identifier (int64) — explain was fully broken on PG18. - feat(pgexplain): render PG18 fields (Disabled, Index Searches, WAL Buffers Full, Storage); broader node-type coverage; fix ModifyTable rendering. - fix(hypo): query hypopg() directly instead of hypopg_list_indexes() (became a view in HypoPG 1.2.0; was failing with SQLSTATE 42883). - ci: PG13-19beta1 EXPLAIN matrix + HypoPG integration test.
