Details:

• Preserve CPU i64 inputs for Select and BitwiseAnd through the precision conversion pipeline so constants are not converted to f64.
• Keep generic oneDNN element-type conversion rejecting i64; use f64 only as an internal 8-byte CPU memory carrier while preserving logical descriptor precision.
• Route i64 Select and BitwiseAnd through reference execution and disable JIT for those i64 cases.
• Add CPU functional coverage for i64 Select, NUMPY broadcast Select, constant broadcast Select, and i64 BitwiseAnd.

AI Assistance:

• AI assistance used: yes
• AI was used to prepare the code/test changes, inspect reviewer risk areas, run duplicate PR checks, and execute local validation. Human validation performed: local diff review, build/test verification, and issue/PR duplicate checks before publishing.
