Input Function Format: Replace Arrow Function with Standard Function Declaration

[RuffLogix]

Because the current version of the input function cannot handle recursion directly, I need to change its format from an arrow function to a standard function declaration.

Current Format

// Current
() => {
    ...
}

Proposed Format

// Proposed
function fn() {
    ...
}

Task

• Implement standard function reader in createBlockModal
• Ensure support for both cases (arrow function and standard function declaration)
