Remove autofix, no longer used

- Add multi-level cache strategy with fallback keys
- Implement conditional installation logic (cache hit/miss)
- Enable cross-job cache sharing to eliminate redundant installs
- Add performance monitoring with timing and status notifications
- Optimize all CI jobs (lint, types, test, test-server, bundle-size)
- Create comprehensive caching strategy documentation

Expected improvements:
- 60-70% reduction in yarn install time across workflows
- Cache hit rate >80% for typical development workflows
- Faster job startup times with shared dependency cache
