chore(release): claudemesh-cli@1.6.0

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.
