Journey: Integrate the Ecosystem: Addons as Substrate

Make lean-ctx the substrate the rest of the ecosystem plugs into. `addon add` wires an external MCP server through the gateway, and ephemeral runners (npx/uvx) install on the first call. A typed `integration` then folds each tool's output into a native surface — Repomix packs reach ctx_expand, Serena and Graphify edges reach ctx_callgraph, Mem0/Cognee memories reach ctx_knowledge, Headroom and RTK register as compressors — so a competing tool becomes one interchangeable component instead of a lock-in.
