test(run): the store rules, stacks and memory, and the review fixes, check by check

StoreRules (23 checks), StacksMemory (24) and ReviewFixes (19), each a
test of its own.

Run and SlotsPlan now have seams that start as the real ones: appReady,
probe, query, bypassesRls, migrationsAtHead, migrationsDrift, treeDrift,
promptFor, runPass, resumable, instrumentPreflight, and a Machine for
SlotsPlan. MigrationsAtHead is split out of MigrationsDrift for it; the
HEAD side is still worked out once per tree and base.

The Postgres stand-in and the raw broker call move to tests/Common, shared
by PgWire and ReviewFixes. ReviewFixes runs this binary as `sql`, and a
real server that resets every connection makes the startup message either
fail to go out or never get its answer - a DbError either way.
