Goal: SELECT COUNT(*) over the base query — no descriptor needed.
Work: wrap the base query (FROM/JOIN/WHERE + value filters) with SELECT COUNT(*). No JOIN-split needed (no related columns selected).
Tests: COUNT shape with/without filters; multi-source sum behavior.
Dependencies: Stage 1 sources (no descriptor), #1409.
