docs: update MCP docs — add rah_get_context, fix local path, auto-create DB

All 3 doc files now list all 12 tools including rah_get_context and
rah_update_edge. Fixed local dev path (was stdio-server.js, now index.js).
Added "What to Expect" sections explaining proactive behavior.
Removed "run app first" requirement since DB auto-creates.

+## What to Expect
+
+Once connected, the MCP server instructs Claude to:
+
+1. **Call `rah_get_context` first** to understand your graph (hub nodes, dimensions, stats)
+2. **Proactively identify valuable information** in conversations and offer to save it
+3. **Search before creating** to avoid duplicates

+
+You don't need to ask Claude to use your knowledge base — it will offer when it spots something worth saving.

 ## Example Usage
 
 Once connected, you can ask your AI assistant:
 
 ```
+"What's in my knowledge graph?"
 "Search RA-H for what I wrote about product strategy"
 "Add this conversation summary to RA-H as a new node"
 "Find all nodes with the 'research' dimension"
