Add /remember, /config commands and memory helper scripts

New commands:
- /remember: Quick shortcut to save to memory (auto-categorizes)
- /config: View and manage configuration settings

New automation scripts:
- memory-add.py: Add items to PA memory with auto-categorization
- memory-list.py: List memory items by category

The /remember command provides a quick way to save:
- "Always use X" → preferences
- "Decided to use X" → decisions
- "Project at ~/path" → projects
- Other → facts
