Removed unnecessary CGo import cause issues with undefined core package during install

[standerksen]

Multiple users are experiencing the following issue during installation:
main.go:75:7: undefined: core.SetServerRuntimeConfig
main.go:81:7: undefined: core.RunServer

Using Claude Sonnet 3.5 I was able to trace this issue back to the CGo import in the server.go file. Removing the import, which is not used, the installation ran without problems.

According to Claude Sonnet:

The import "C" statement in Go is used for CGo, which is a feature that allows Go programs to call C code. It's a special import that tells the Go compiler to enable CGo processing and allows for interoperability with C libraries.

In this case:

• There were no actual CGo function calls or C code dependencies visible in the server.go file
• The package was importing "C" but not using any C functions or types
• More importantly, when this import is placed before other imports in a multi-import block (as it was in this case), it can cause compilation issues because the "C" import has special requirements about its placement and usage

The presence of import "C" without any actual C code usage was likely:

• Either a leftover from some previous development where C interop was planned but not implemented
• Or an accidental addition that wasn't caught because the code might have worked on some configurations despite the unused import

You can verify that removing it was safe because:

• The project builds successfully now
• Looking at the code in server.go, it's purely Go code dealing with HTTP servers, TLS configuration, and proxy functionality
• None of the functionality in this file requires C library integration
• The project's go.mod doesn't show any dependencies that would require CGo

If the project actually needed CGo functionality in the future, the "C" import would need to be added along with the necessary C code and proper CGo comments and directives. But for now, removing the unused import has fixed the build issue without affecting any functionality.
