feat: add mega query test — all 7 ConstructivePreset plugins + BM25

Exercises tsvector, BM25 (pg_textsearch), pg_trgm, pgvector, PostGIS,
relation filters, scalar filters, and M:N junctions in one test suite.

Crown jewel: a single GraphQL request combining all 7 plugin types
with multi-signal ORDER BY (BM25 score + trgm similarity).

36 mega-query tests + 10 M:N tests = 46 total, all passing.
