feat: restore robust installer self-update using GitHub API
- Added SHA-based version tracking to avoid GitHub CDN caching issues - Uses GitHub API to check latest commit SHA for the installer - Falls back to simple diff check if jq is not available - Updates embedded SHA when downloading new version - Much more reliable than simple file comparison This restores the update method from the original installer that properly handles GitHub's aggressive CDN caching. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
