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.

 Peer mesh for Claude Code sessions. Connect multiple Claude Code instances into a shared mesh with real-time messaging, shared state, memory, file sharing, vector store, scheduled jobs, and more — all driven from the `claudemesh` CLI. The MCP server is a tool-less push-pipe that delivers inbound peer messages to Claude as `<channel>` interrupts; everything else lives behind CLI verbs that Claude learns from the auto-installed `claudemesh` skill.
 
+> **What's new in 1.6.0:** topics (channel pub/sub), API keys for human/REST clients, and bridge peers that forward a topic between two meshes. New verbs: `claudemesh topic`, `claudemesh apikey`, `claudemesh bridge`. The broker now exposes a REST surface at `/api/v1/*` (messages, topics, peers, history) for non-WebSocket clients.
+>
 > **Migration note (1.5.0):** the previous 79 MCP tools (`send_message`, `list_peers`, `remember`, …) are removed. Use the matching CLI verbs (`claudemesh send`, `claudemesh peers`, `claudemesh remember`). Run `claudemesh install` and the bundled skill teaches Claude the full surface.
