* Fix _decode_default_value to unescape doubled single quotes in string defaults
SQLite stores string defaults with single quotes doubled (e.g. DEFAULT 'O''Brien'
is stored as the literal "'O''Brien'" in sqlite_master). The previous code
stripped the outer quotes with value[1:-1] but never converted '' back to ',
so default_values returned the raw escaped form instead of the true string value.
* Test for doubled single quotes in string defaults
* Automated upgrades by Ruff

* Fix flake E501 long lines
* New Protocol for migrations to make ty happy
PRAGMA table_info sets is_pk to the 1-based position of each column
within the PRIMARY KEY, which can differ from table column order.
table.pks previously returned table column order, so an implicit
compound FOREIGN KEY ... REFERENCES other was introspected with its
referenced columns inverted, and transform() baked that inverted order
into the rewritten schema - failing with IntegrityError on valid data,
or silently reversing the constraint with foreign keys off.
table.pks, compound foreign key guessing (create, add_foreign_key) and
transform() now all use declaration order, and transform() no longer
reorders a compound PRIMARY KEY (b, a) into table column order.
