#3350 fix(mappers): Configuration schema now reflects that casting to `bool(...)` in stream map `__filter__` expressions is not required Pull request opened by edgarrmondragon ## Summary by Sourcery Allow stream map filters to be specified without wrapping in bool() by relaxing the JSON schema and adjusting parser logic, fix ArrayType usage for key_properties, and expand tests to cover both casting and non-casting filter expressions. Bug Fixes: • Relax filter schema to accept any expression instead of enforcing bool() wrapper • Simplify mapper logic to pop and parse filter expressions directly, supporting plain boolean expressions • Correct ArrayType instantiation for key_properties property Tests: • Adjust tests to use plain filter expressions and add a case for backward-compatible bool() casting meltano/sdk
