The CLI validated --stop-before names against both pending and applied
migrations, but Migrations.apply() only looked for the stop name among
pending ones - naming an applied migration passed validation and then
silently applied every migration after it, the exact outcome the option
exists to prevent. apply() now raises ValueError before applying
anything if a stop_before name matches an applied migration in its set;
names not in the set are still ignored, since unqualified CLI values are
offered to every set. The migrate command reports it as a clean error.

pending() and applied() no longer create the _sqlite_migrations
table or perform the one-way legacy schema upgrade - that now only
happens in apply(). The CLI --list path no longer creates the
database file when it does not exist. applied() results are now
explicitly ordered by insertion.

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.
