#### Block Way Implementation ✎
- Implemented the `BlockWay` function to extract variant type information from block inputs, returning either tuple indices or struct member names
- Added type annotation support for `BlockWay` operations with proper handling of optional variants and different underlying types
- Introduced computation node implementation for `BlockWay` that processes both tuple and struct variants efficiently
- Enhanced runtime version handling to support the new `BlockWay` functionality with version 80
- Added comprehensive unit tests covering various scenarios including tuple variants, struct variants, optional variants, and edge cases
- Integrated `BlockWay` into the SQL parser and program builder with proper type inference and validation
- Added SQL format tests and canonical data for tuple and struct variant scenarios with and without optionality
