Feature: CI/CD upgrade path for upstream synchronization

[ZZirbel]

Summary

Automated upgrade path for keeping Claude Code config in sync with upstream aaronsb/claude-code-config.

Current Architecture

• ~/.claude/ is a git clone of ZZirbel/claude-code-config (personal fork)
• ccupdate pulls latest from the fork
• Fork syncs from upstream via GitHub Actions

Implemented

GitHub Actions Upstream Sync

• .github/workflows/upstream-sync.yml — daily cron job
• Detects upstream changes, creates PR for review
• Auto-merge for data files, manual review for code changes
• Status: Workflow exists, needs testing

PowerShell Startup Check

• Show-ClaudeConfigStatusOnStartup in profile
• Shows notification when config is behind upstream
• User runs ccupdate to pull changes
• Status: Working

Acceptance Criteria

• Upstream sync workflow tested and working
• Startup notification working correctly
• Documentation for manual vs automated sync options
