fix: resolve RedisCache array offset error and improve discovery diagnostics

- Fix RedisCache driver to handle MGET failures gracefully with fallback
- Add comprehensive discovery context comparison debug tools
- Identify root cause: WEB context discovery missing 166 items vs CLI
- WEB context missing RequestFactory class entirely (52 vs 69 commands)
- Improved exception handling with detailed binding diagnostics
