feat: Remove dangerous getAllNouns/getAllVerbs methods, add safe pagination

BREAKING CHANGE: Removed getAllNouns() and getAllVerbs() from StorageAdapter interface
These methods could cause expensive full scans on cloud storage (S3/R2) leading to
high costs and performance issues. Replaced with safe paginated methods.

Changes:
- Remove getAllNouns/getAllVerbs from StorageAdapter interface and implementations
- Add internal optimization methods for intelligent preloading when safe
- Fix OPFS storage file naming consistency (.json extension)
- Fix S3 high-volume mode detection thresholds (was too aggressive)
- Fix TypeScript compilation errors with async methods
- Update all tests to use paginated methods

Performance:
- Add smart dataset size detection for automatic optimization
- Maintain all internal performance optimizations through safe preloading
- Only preload data in read-only mode or when dataset is small (<10k entities)

Fixes:
- Fix intelligent verb scoring tests metadata structure
- Fix S3 storage getVerbsBySource/Target/Type methods
- Fix memory usage in search operations using pagination

Docs:
- Add comprehensive storage architecture documentation
- Document known bash redirection issue
- Update README with architecture doc link

All affected tests passing
