* Add parsing for triple-quoted table notes in DBML
* Update writer to format multiline notes correctly
* Enhance tests for multiline table notes handling
* Add handling for pgvector and PostGIS extensions in migration scripts
* Implement operator class and storage parameters for vector indexes
* Update tests to validate new index behaviors and extension creation
A composite [pk] entry inside an Indexes block (e.g. (a, b) [pk]) was
silently dropped: models.Index has no way to represent a primary key,
so the attribute was parsed and ignored, producing neither a PK nor a
meaningful index. It's now converted into a PrimaryKeyConstraint.
Also, Column.Sequence was never set by the DBML reader, so composite
PKs assembled from column-level [pk] attributes fell back to
alphabetical Name sorting instead of declaration order. Columns now
get a per-table sequence counter reflecting the order they were
declared.
* Implement tests to ensure explicit type modifiers are preserved during conversion.
* Validate behavior for varchar, numeric, and custom vector types.
* Log statement type during execution for better debugging
* Introduce detectStatementType function to categorize SQL statements
* Update unique constraint naming convention in tests
* Implement check constraints in the schema writer.
* Generate SQL statements to add check constraints if they do not exist.
* Add tests to verify correct generation of check constraints.
