Rename SwiftGitX enum to SwiftGitXRuntime

[ibrahimcetin]

Problem

The SwiftGitX enum name conflicts with the module name, making it impossible to reference module-level types when the enum is in scope. This particularly affects tests using Swift Testing where Testing.Tag and SwiftGitX.Tag create ambiguity.

Before - Ambiguous, doesn't work

let tag = try #require(references.first as? SwiftGitX.Tag)
// Error: SwiftGitX.Tag resolves to the enum, not the module

Solution

Rename the enum to SwiftGitXRuntime to eliminate the naming conflict.

After - Clear and unambiguous

try SwiftGitXRuntime.initialize()
let tag = try #require(references.first as? SwiftGitX.Tag)
// SwiftGitX now correctly resolves to the module

Breaking Changes

Simply rename SwiftGitX to SwiftGitXRuntime.

Pull request overview

This PR resolves a naming conflict between the SwiftGitX enum and the SwiftGitX module by renaming the enum to SwiftGitXRuntime. This prevents ambiguity when trying to reference module-level types, particularly in Swift Testing contexts where Testing.Tag and SwiftGitX.Tag would collide.

Key changes:

• Renamed the SwiftGitX enum to SwiftGitXRuntime in the main source file
• Updated all test references to use the new SwiftGitXRuntime name
• Maintained backward-compatible documentation comments that refer to "the SwiftGitX library" (the module)
