feat(v1.1): consolidate 29 tools → 8 unified tools + CLI

Tool Consolidation:
- search: merges recall, semantic_search, hybrid_search
- memory: merges get_knowledge, delete_knowledge, get_memory_state
- codebase: merges remember_pattern, remember_decision, get_codebase_context
- intention: merges all 5 intention tools into action-based API

New CLI Binary:
- vestige stats [--tagging] [--states]
- vestige health
- vestige consolidate
- vestige restore <file>

Documentation:
- Verify all neuroscience claims against codebase
- Fix Memory States table: "Retention" → "Accessibility" with formula
- Clarify Spreading Activation: embedding similarity vs full network module
- Update Synaptic Tagging: clarify 9h/2h implementation vs biology
- Add comprehensive FAQ with 30+ questions
- Add storage modes: global, per-project, multi-Claude household
- Add CLAUDE.md setup instructions
