feat: add BushelKit 3.0.0-alpha.1 dependency

Add BushelKit to Package.swift dependencies for ecosystem integration.

BushelKit provides:
- BushelLogging - Logging infrastructure using FelinePine
- BushelFoundation - Core foundation library
- BushelUtilities - Shared utility functions
- And 14 other products for VM management

This establishes the foundation for future integration with the
broader Bushel ecosystem while keeping BushelCloud focused on its
CloudKit demonstration purpose.
