Release v0.17.0

[pusewicz]

Release v0.17.0

Added

• SHA-based caching for downloaded Cute Framework headers - checks GitHub API for latest commit SHA before downloading to avoid redundant fetches
• GitHub API client with optional GITHUB_TOKEN support for higher rate limits (5000/hr vs 60/hr unauthenticated)
• Metadata tracking (.cf-mcp-sha file) stores downloaded version SHA for cache validation

Changed

• Downloader uses commit-specific archive URLs (e.g., /archive/abc1234.zip) instead of always downloading master branch
• Download process now checks for updates by comparing stored SHA with latest GitHub commit
• Refactored all internal require_relative statements to use autoload for lazy loading, improving load time and memory usage
