feat: add configurable mockPrefix to Cuckoofile.toml

[mmustafasenoglu]

Summary

Add a global mockPrefix option to Cuckoofile.toml that allows customizing the prefix of generated mock class names.

Closes #564

Changes

• Module.swift: Added mockPrefix to DTO.Options and Options structs
• HasName.swift: Changed mockName to use Module.mockPrefix instead of hardcoded "Mock"
• GenerateCommand.swift: Added parsing for global mockPrefix TOML key
• Cuckoofile.toml: Added documented mockPrefix option

Usage

# Global prefix (default: "Mock")
mockPrefix = "Fake"

[modules.MyProject]
output = "GeneratedMocks.swift"

This generates FakeGreeter instead of MockGreeter.

Backward Compatibility

• Default value is "Mock", preserving existing behavior
• No changes to generated output when mockPrefix is not specified

Hi @MatyasKriz, thanks for taking a look!

That's great to hear you had planned this for 2.0. I've implemented the mockPrefix config option in Cuckoofile.toml that lets users customize the prefix (defaults to "Mock").

I've also added a basic test case for the prefix configuration. Happy to adjust the implementation if you'd prefer a different approach. Let me know how you'd like to proceed with testing on your end.

@mzschwartz5 Thanks for taking a look!

We didn't actually change any defaults, right?

Correct - no defaults were changed. The default prefix stays as "Mock", preserving full backward compatibility. We only exposed the ability to customize it via the mockPrefix option in Cuckoofile.toml.

@mmustafasenoglu I think you're conflating a couple PRs here. I imagine you meant to respond to me here
