Wires the curation primitives into the MCP surface (all three sites: tools() descriptors, handleCall dispatch, package doc) and registers the GET /pending + POST /promote REST routes. brain_promote additionally re-indexes the promoted note into the graph (best-effort), matching the other write paths. brain_pending is the human-review-queue complement to the agent-facing brain_write.
