Enhanced Function Signature Interpretation and Execution

[JohnnyIrvin]

The shell-craft project currently facilitates the execution of shell commands and template autofill via OpenAI's API. To extend its utility for developers, I suggest adding a feature that allows the tool to interpret function-like prompts that include a function signature and arguments for execution.

Proposed Solution
Modify the shell-craft tool to parse prompts that mimic a function call, extract the function name, arguments, and return type, and execute them. This functionality would emulate calling a function in a traditional programming environment

Example Usage

shell-craft --prompt function "add(int a, int b) -> int: add(5, 6)"

The tool would interpret this prompt and execute a function add with the provided arguments 5 and 6, expecting an integer return type.
