fix: Use explicit Package.Dependency type to avoid Swift 6.2.3 circular reference bug (#11)

## Problem
The pattern `.package(url:...)` inside `package.dependencies.append()` causes Swift 6.2.3 to confuse the member lookup with the `package` variable, resulting in a "circular reference" error.

## Solution
Use the explicit type `Package.Dependency.package(url:...)` to avoid this ambiguity.

## Testing
- Verified Package.swift parses correctly with Swift 6.2.3
