catlog22 7e70e4c299 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
