Overview

Ensures N test databases exist, one per worker slot, by spawning a Rails db setup process per slot (each with its own TEST_ENV_NUMBER).

The result is cached by a fingerprint of db/schema.rb + db/seeds.rb plus the worker count, so repeat runs skip setup entirely. Set RSPEC_TURBO_FORCE_SETUP=1 to force recreation.
