Pull request overview

This PR adds support for ENUM column types to the Yiisoft SQLite database driver. Since SQLite doesn't have a native ENUM type, the implementation detects CHECK constraints with IN clauses and treats columns with such constraints as enumeration types. This is a breaking change that removes the previous mapping of 'enum' to string type.

Key changes:

• Implements enum value extraction from CHECK constraints using regex pattern matching
• Maps ENUM column type to 'varchar' in schema definitions
• Adds comprehensive test coverage for various CHECK constraint formats
