The v0.2.0 backend cut. Topics, API keys, REST /api/v1/*, and bridge peers — all in one CLI release. Adds three new verb namespaces: topic (channel pub/sub), apikey (REST client auth), bridge (cross-mesh forwarding). Also pins @claudemesh/sdk as a workspace devDependency so the bridge implementation is bundled by Bun at build time and doesn't leak into the npm tarball's runtime deps.
