Commit Message

perf(dbms): plan composite, union, intersection, null, and covering index reads (#178)

Queries, updates, and deletes now use composite indexes from their leading columns, union index lookups for OR, intersect separate indexes for AND, read IS NULL and IS NOT NULL through indexes, and build covered projections from index keys without loading records. Candidate sets are bounded and fall back to a scan instead of truncating, every candidate is re-checked against the whole filter, and transaction changes are reconciled by visible row identity. LIKE and JSON filters keep the previous single-column behavior. A new index_planning Criterion suite and access counters measure the change against a baseline that already includes #175.

closes #69
