An unknown --stop-before value previously matched nothing and every
migration was silently applied, including the one the user meant to
stop before. The CLI now errors unless each value matches a known
migration.
The CLI also always passed stop_before as a list, but older
duck-typed sqlite-migrate Migrations objects compare it against a
single string name - so the flag was silently ignored for exactly
the migration files the compatibility shim exists to support. Legacy
sets now receive a single string, with an error if multiple values
target one legacy set.
