pgrls 0.37.0

Static analyzer for Postgres Row-Level Security — 60 lint rules for tenant and per-user row-scoping bugs, performance traps, and hygiene (18 auto-fixable); a Z3 tenant-isolation prover (pgrls verify) that proves no row leaks to an anonymous session or across tenants, or shows the leaking row; gold-standard RLS scaffolding (pgrls generate); runtime seq-scan analysis (pgrls perf); a semantic policy-diff command for CI gating; and a pytest plugin for RLS isolation tests.
