Fixes two critical production bugs in GCS storage adapter:
1. brain.find({ where: {...} }) returned empty array after restart
- Root cause: Counts only persisted every 10 operations
- If <10 entities added before restart, counts were lost
- After restart: totalNounCount = 0, causing empty results
2. brain.init() returned 0 entities after container restart
- Same root cause as bug #1
- Counts file never written for small datasets
- getStats() returned 0 despite data in GCS bucket
Changes:
- baseStorageAdapter.ts: Persist counts on EVERY operation (not every 10)
- incrementEntityCountSafe(): Now persists immediately
- decrementEntityCountSafe(): Now persists immediately
- incrementVerbCount(): Now persists immediately
- decrementVerbCount(): Now persists immediately
- gcsStorage.ts: Better error handling for count initialization
- initializeCounts(): Fail loudly on network/permission errors
- initializeCountsFromScan(): Throw on scan failures instead of silent fail
- Added recovery logic with bucket scan fallback
Impact: Critical for serverless/containerized deployments (Cloud Run, Fargate, Lambda)
where containers restart frequently. The basic write→restart→read scenario now works.
