Refactor get function signatures in tuple.h for improved type deduction

- Updated `get` function signatures to return `auto&&` instead of `decltype(auto)` for better type handling.
- Enhanced consistency across all overloads of `get` by applying uniform return types.
- Minor adjustments made to improve readability and maintainability of the code.
