perf(ccw): optimize I/O operations and add caching layer
Performance Optimizations:
1. Async I/O Operations (data-aggregator.ts, session-scanner.ts):
- Replace sync fs operations with fs/promises
- Parallelize file reads with Promise.all()
- Add concurrency limiting to prevent overwhelming system
- Non-blocking event loop during aggregation
2. Data Caching Layer (cache-manager.ts):
- New CacheManager<T> class for dashboard data caching
- File timestamp tracking for change detection
- TTL-based expiration (5 minutes default)
- Automatic invalidation when files change
- Cache location: .workflow/.ccw-cache/
3. CLI Executor Optimization (cli-executor.ts):
- Tool availability caching with 5-minute TTL
- Avoid repeated process spawning for where/which checks
- Memory cache for frequently checked tools
Expected Performance Improvements:
- Data aggregation: 10x-50x faster with async I/O
- Cache hits: <5ms vs 200-500ms (40-100x improvement)
- CLI tool checks: <1ms cached vs 200-500ms
