Add a comprehensive set of SQL scalar/aggregate functions (string, numeric, null-handling, CASE, group_concat/string_agg, COUNT DISTINCT) comparable to a general-purpose RDBMS. Also wire ZoneMaps into SqlEngine so a single, non-joined `SELECT ... FROM blocks` can skip whole documents based on `lang`, `depth`, or heading `content` predicates without scanning their blocks. Joins always disable this skip to avoid alias ambiguity.
