fix: resolve MCP output validation errors in HTTP server

Browse Source 
- Rename `content` → `notes` in searchNodes and getNodes output schemas
  to match what the handlers actually return (was causing validation errors)
- Rename `schema` → `stats` key in rah_get_context outputSchema and
  structuredContent return (schema key name confused MCP SDK validator,
  caused getContext failures for external users like Linux)
