feat(cache-status): remove irrelevant size column and add disk cache scanning

The cache-status command now provides a cleaner, more focused display by removing the irrelevant 'Size (bytes)' column that always showed zero. Additionally, it now scans disk for all transaction caches, ensuring comprehensive visibility into both in-memory and persisted cache data. Users can now quickly assess their cache state without distraction from meaningless data.

 **Objective**: Implement status overview and cache inspection commands.

 1. ✅ Implement `accounts status` command aggregating account data from adapters
 2. ✅ Add cache inspection functionality to `transactions cache-status` (shows in-memory caches only)
-3. ❌ Fix `transactions cache-status` to scan disk for all transaction caches (currently missing disk-based caches)

 **Current Status:**
 - `accounts status` works and shows account sync status
-- `transactions cache-status` exists but only shows in-memory caches; needs disk scanning to be useful
+- `transactions cache-status` now shows comprehensive cache information including disk-based caches
+- Removed unused `transactions clear-cache` command
 
 **Testing:**
 - Unit tests for status aggregation logic

 ## Completion Notes
 
-- **Phase 5 Fix Required**: Update `GoCardlessAdapter::get_cache_info()` to scan cache directory and load all transaction caches from disk (similar to `get_transaction_info()` fix)
+- **Phase 5 Fix Required**: ✅ COMPLETED - Updated `GoCardlessAdapter::get_cache_info()` to load all transaction caches from discovered accounts (both in-memory and disk-based)
 - **Remove Cache Clearing**: ✅ COMPLETED - Removed `transactions clear-cache` command from CLI as it's not useful
-- **Status Metrics**: Consider adding sync health metrics beyond account status
+- **Status Metrics**: Deferred - current AccountStatus provides adequate sync health information
 - **Multi-Source Ready**: Architecture supports adding CSV, CAMT.053, MT940 adapters when needed</content>
