revert: remove GSD Memory system (not ready for release)

Reverts af7a057 "feat: add GSD Memory cross-project knowledge system"

The memory system needs more work before shipping:
- Workflow integration is incomplete (writes but doesn't query)
- UX requires too much manual intervention
- Setup friction exceeds value for most users

Preserved on branch `memory-wip` for continued development.
